The most special day in my life would have to be the day my son was born. I was happy, excited, nervous and jittery as all hell. Then I get phone calls from everyone and thier friggin' grandma, sayin', "She's havin' the baby!!" As I'm leaving to go to the hospital, LOL.
That was the very first time I held my son in my arms. It was the greatest ever! So on a technical level, my son's b-day would be the most special day. And hey! I get to celebrate it on a annual basis! LOL.
