2+1=3

Today Joshua is 21, or 3, depending on whether you are referring to his biological age(21) or the age his actions portray(3). That is all. He does not need too much attention, for otherwise:
1) His head inflates like one of those balloons clowns turn into animals (and eventually explodes so this might not be too bad after all)

or





2) He cries his little baby eyes out because everyone is picking on him (waaaaaaaaaaaaaa)
