You were walking to the place you and your best friend decide to meet. Then you noticed your friend standing there. You decided to surprise him

You walked closer. Then you jumped on his back and wrapped your arms around his neck. He put his arms under your legs so as not to drop you. When he turned around you noticed it wasn't your friend as he looked at you with a weird expression

You felt your face got red when you realized you mistook a stranger as your best friend. So embarrassing..
