Do you have a doppelganger?

I'm constantly being told I look like some girl named Jenna when I'm out in public.. It's getting a little creepy.Do you have a doppelganger?
ppl always say they knew someone in their old skool that looked exactly like me but they act like the total opposite of me.Do you have a doppelganger?
I get that too..it's always...do you have a brother named (insert name here)



I just tell them...Maybe...dad use to get around a lot.
