Dear Little Sim,
Yes, I realize you're experiencing extreme happiness about that great meal, the pretty pictures on the wall, the fact you just had your first kiss, your first girlfriend, your first BFF, got engaged, then married and woo hoo'ed for the first time.
Yes, I know you're now feeling very playful after telling that joke and having it amplified by the aforementioned happiness, but please, PLEASE stop getting hysterical over it all. I've sent you to calm yourself down in a mirror three times now and I'm scared one of these times you're not going to make it and then d... I can't even say it.
Your wife needs you, I need you, and by the way, she hasn't told you yet, but you're going to be a Dad too, so... WAIT! Oh No, oh darn...
I shouldn't have said that... *sigh*
