One reason humor came to the fore in my response is that seeing the starkness of "I suck" is a bit of a trigger for me. When My Son was about 10 years old, he went through a phase in which every other sentence was, "I suck." Delivered in a dramatically drab, ennervated monotone worthy of Eeyore--except, of course, that Eeyore would never say "I suck." ;-) It took My Son a month or two to get tired of saying that all the time and move on to the next verbal fad, but as you can see the memory lingers on.
O.K., I have to tell you this...
