If the ref was just standing there smiling, there may be more to the situation than we are aware of. An example of something similar to this that happened to me might explain why no call. I was working a friday night home game for a team that I also called on Tuesday night as the visitior. They won big during the Tuesday night game largely because the opposing team in that game thought we were horrible and picked up a number of T's that cost them their coach and their best player (he was hanging on the rim for the first T, which caused a massive chain reaction from the coach, bench and player). By the end of the game the home crowd was all over us. Well come Friday night, one of the players of the team that won on Tues night saw us come on to the court and exclaimed "these are the guys that about got killed last game. I hear they really blew that game". We both just laughed because we realized the nature of his comment.

Normally, I would say this is worthy of a T, but the situation, tone, etc, should help clarify. If you had worked one of their previous games and were met with dissatisfaction then the comment is probably intended to be negative and thus worthy of the T. It might just be a case of the kid jokingly giving you a hard time.
