What sign are you?

I was born on my parents' 8th wedding anniversary...third child...following my two brothers ... 11:02 AM on a Tuesday morning. Birth order: the baby of the family...later to be established as the 'lefty' of the family.
I used to call my mom on the phone at 11:02 every year and sing 'Happy Birthday' to her since she birthed me and she was happy about it.
I'll be singing at 11:02 tomorrow just because...that's my thing.
Twenty-nine years later, my son was born three days before my birthday. So really I was three days shy of thirty!! I remember it well.
Where does the time go?
Even though the years add up..somehow we do not feel the age we are. At least...I don't.
If I were to pick one defining characteristic that defines me, it would be my ability/compulsion to burst into song depending on whatever 'word' has been spoken. There was no surplus of money in our house and Catholic school had no music in their program. I often tell Mom that if she had cultivated my musical talents, we'd be living in a house on some beautiful body of water!!
What would be your signature defining trait? Don't think too long...it should pop right into your mind.
