I spent all day (from 7AM to 6PM) babysitting a 3 year old and a 5 year old. Boys. Is it really possible to have that much energy? Sweetest kids, really, but dear Lord! And while I have tomorrow off for my b-day, I have them again the rest of the week and all of next week and the week after. Oh, and I might babysit another kid (age: 4) in the evenings sometimes.
Who needs birth control? Just babysit!
