Last Friday me and my mom went shopping. I wanted to buy a winter coat for myself. As I walked into the store I noticed my mom talking with some guy. He didn't look like he was shop assistant. It was really strange, because I've never seen him before.
I came closer and then that guy looked at me. 
"Oh my God, you're grown up already!" Said that man with a smile on his face.
"That's your uncle Sasha." said mom.
"Oh, you don't remember me?" The guy looked into me eyes and smiled. 
"I don't" I answered. 
"It's ok. You were really small when we've last met." He said. "So I need to go." 
"Goodbye" we said.
