OH MY GOD YOU GUYS!!!!!!
Er, pardon the caps lock and excessive exclamation marks, I'm just really happy now.
My mother sent an email to my grandparents, explaining that I am a guy.
Their response: "Wow, what a great present for our 49th anniversary! Not everyone gets a handsome, intelligent young man for their anniversary! We hope you are doing well, feel free to visit."
THIS IS WONDERFUL!!
