Well, my husband would probably say I'm
rand()
because he never knows what he's going to get... especially during a certain week of the month.
Or perhaps he would say I'm
user_error() or trigger_error()
because I'm the first to issue any warnings or point out any errors for behavior he might be exerting at the time.
But I'd say I'm closer to
pspell_check()
because I seem to be the person everyone in the office yells to for the correct spellings of words.
