thanks - WTF?

100NL, PP 6MAX.

Effective Stacks 100.

Reads: Very little, my first orbit at table, villian has big stack $450 and played 4 of 5 hands. So very little.

PF: One limper to hero in SB, I raise to 5 w AKo, villain in BB calls, limper folds.

Flop: A25r ($11 in pot)

I lead for 10, villian pushes, as I think about the call, villian types 'thanks' in the chat box.

WTF? Thoughts? First level thinking is that he's expecting a call, is he trying to fool me into folding?
