when you report a bug via perlbug system, and it gets fixed, a message comes that you should not tell your sympathies to a person that fixed your bug via perlbug but rather tell him directly.
The funniest thing here is that this systems assumes that you want to say something like "I owe you a beer" or "I want to have your child" :)

Same thing applies to your thoughts, I think. You could just bring a couple of beer.
Or whatever...
