I gave a pat on the back and said “hey how are you?” To realize to my horror I did not actually know this person who I thought I knew. It still keeps me up at night.

that pic hurts but i approve of the funny

This is for the best. Just imagine if it were a hug instead.

Luckily she was made out of cake.

I once got genuinely hugged from behind by a girl thinking I was her BF. Kinda fun because I was waiting for my Gf to arrive and first assumed it would be her. The other girl also had a similar height and hair color xD

Pretend that you waved another person behind them

What a painting though

does anyone know the original artwork?

NO, in fact everyone but you!
