When Han shot a cold look towards him Suigetsu momentarily thought she might have been a water bender. He could have sworn the fluid around his testicles froze.
He shook off the feeling as best he could and noted that it was possible for Han to accept a nickname, but not from him.

He thought he'd made some horrible and ever-lasting damage to their relationship until Han asked him if he was hungry. At first he wasn't sure if she was still talking to herself since the transition was so abrupt.
Suigetsu thought about the idea of a tryst involving his two co-workers killing his appetite at breakfast and then to the stick of grilled unagi he had earlier. He was hungry.

"Come, we'll eat before I let you teach me how to ask people questions."
At first Suigetsu could only gape at Han's statement. Once he sat down he could speak, but her request still made no sense.
"Teach? You?"
The shock had worn off and the absurdity had set in. Suigetsu, the perpetual student, the perpetual poor student teaching someone. He had to laugh. There was no way for Han to know his history and how many frustrated teachers he had in his time, but it was still highly amusing.
His laughter died down and he felt a little ashamed with his reaction.

"Sorry, but I don't know what I can teach you. You don't know me well, but I'm not smart and I don't know if I can actually teach what I know. Even if it's not much." He sighed and wished he'd answered Han with at least an iota of confidence.

A waiter approached barefooted and utilizing a wobbling walk which made Suigetsu smile. It was blindingly obvious what the problem was, even to him. Han knew it too, most likely due to the same, but deeper observations.
"Just started earth bending classes, huh? I know that 'horse stance' walk."
Though he would never be able to bend earth Suigetsu took the running joke of him being a lost earth bender seriously. He knew the forms and stances and was even told he had some talent for it. He couldn't care less if is waiter were an aspiring water bender, but Suigetsu felt it was good to encourage earth benders to persevere.

After taking whatever the student waiter suggested and as Han ordered her meal Suigetsu decided that he had stumbled upon something. Maybe he did have something to teach. Once the waiter left he tried to think of a lesson to impart.
"I guess the first thing to remember is that people love to talk about themselves...most people. If you show some interest they will usually go on and on about stuff. You're pretty so you have a huge advantage...kinda. If you deal with guys they're probably going to lie to try to impress you. By now you probably know that guys will just about anything for a pretty woman."

When the shuffling waiter came back with their drinks Suigetsu spent a few minutes detailing his trials of earth bending classes which he assumed would put the server at ease.
"People love embarrassing stories where they can feel superior. Unfortunately, I have a ton of those. Like at the unagi stand. I told the guy that..." he froze momentarily and tried to think of a vague way to refer to Han and hoped it would escape her notice. "um, that there was someone I, uh, liked a lot. I also mentioned that I had no chance. He felt bad for me and gave me a stick of unagi. Even though times were bad for him he felt I had things worse. You can't just go around complaining, you have to do it right."

The water bender sighed and wondered if he was making any sense. Human interaction was hard. Teaching it was even harder. He could only hope that with Han's observational skills she could learn what he did without him having to speak it.
He spoke further with the waiter and found out where he studied and the circumstances of him discovering his ability to bend. Suigetsu asked more questions and threw in the occasional anecdote and found the waiter opening up to him perhaps too much. Apparently, there had been a fight with his boyfriend the mention of which made Suigetsu very uncomfortable. People getting that personal that fast unsettled him.

"Why don't we trade questions to practice? I'll ask one and then you." It seemed like a useful means of sharpening Han's social skills. More importantly, it was a good pretense to get to know the woman across from him better.

"What do you look for in a man?"
He wanted to gouge out his eyes with his chopsticks for not building up to that question, but it was out there begging to be asked.
