Adults should make an effort. If I see an adult wearing a cartoon character on the front of their shirt, the same design as what an infant wears, then I judge them. And I should.

My theory is that the simplest explanation for this is that some people are just stupid and they are unaware that there is a time and a place for that sort of thing, and that time is not in a grocery store and that place is not outside of your bedroom, and most certainly not on an airplane.<br><br>My theory has nothing to do with the perceived maturity level of cartoon characters, or how serious or trivial the subject of the cartoon is. Or what the characters do and how they relate to adults.<br><br>The theory is that adults are wearing an article of clothing that was designed for babies. If you are an adult wearing a shirt with Tom Brady or Bart Simpson on it, well some company made that shirt for an infant first, and then decided to also include larger sizes for adults who must continue to wear them because some people don't know better or don't care.<br><br>Every time I see an adult wearing one of these shirts in a public place, I feel embarrassed for them.
