April 21 is Sam's birthday. Sam is one of the best woman to exist in the history of humanity. She's pretty, autistic, short, attentive, charming, caring, compassionate, did I mention short? But yeah, as I said before she may be a little short and a tid special, but she is the kindest girl who tries to make everyone around her feel better.
"Don't you know Sam's birthday is today, it's April 21st!"
