TIFU by trying to look cool in front of my daughters friends

I (44F) live in Belgrade. My daughter (19) is in Novi Sad but sometimes she comes home with friends. Whatever, normal.

So last weekend she comes with two friends, both guys. One of them is... ok I'll be honest. Really good looking. Like stupid good looking. I'm 44 not dead.

Anyway they're all sitting in living room, I'm in kitchen making coffee, trying to be the cool mom. I bring them coffee, we talk a little. The hot one says something about Serbian coffee being strong. I say "yeah we like it strong here. like our men."

I thought I ATE. I thought I was so smooth. I literally turned around to walk away like I just dropped the mic.

I didn't see the door frame.

I walked straight into it. FULL FORCE. Coffee tray goes flying. I fall backwards. My robe opens. I'm on the floor, legs everywhere, robe open, coffee all over me, and these three 20 year olds just staring at me in complete silence.

My daughter goes "...mama... are you ok"

I wasn't ok. I have never been less ok. I just got up, said "I'm fine don't move I'll clean later" and walked to my room and didn't come out for 3 hours.

The hot one kept looking at me the rest of the weekend. Not in a good way. In a "I just saw my friends mom naked on the floor" way.

I'm moving to another country.

TL;DR: tried to be cool in front of my daughters hot friend, walked into a door frame, fell, robe opened, now I can never show my face again.
