OMG, lol. I have a sister, and I once went to my hometown to visit but told nobody!! I was in a bar downtown in Sacramento, I had a guy approach and ask if I was related to........ (my sisters name)!! I was like ummm no, lol. He said wow you look so much like her. So I tried to avoid him, but after a few drinks and dancing, I ended up blowing him in the parking lot. lol.
My sister sends a group text to us all the next day saying... my friend said he ran into a girl that looked like my twin, lol. She actually asked if we had a sister!!!!
