Nah, not mad. i just think its no ones business if a students wants to do something for his or her sifu. no students HAVE TO do anything. even when they pay they don't HAVE TO show up. but they do.
the idea of doing something for your teacher upsets or disturbs some people is silly as fuk.
one of my students knows i LOVE ME SOME PASKRAMI SAMMICHES.....and regularly asks if i would like one from the place he goes to. sheeeeeet.....i gets hooked up!
