This has to be the most embarrassing thing that has EVER happened to me!
I was on holliday in Spain last summer and the hotel room I was staying in had these double doors that led out onto my own balcony overlooking the hotel pool.
Well this one day i had just finished taking a shower and came out wearing only a towel. I thought I had left my clean clothes drying on the line on the balcony and so i went out through the doors to fetch them so I could get dressed but as i stepped out onto the balcony my towel slipped off and got caught in the doors as they swung shut behind me. I dived to open the door so i could get back inside and hide but my towel was wedged in the door and had jamed it - I couldn't get it open! To make matters worse I realsied I hadn't actually left my clean clothes out there and so I couldn't even grab them to hide my blushes.
So there I was left standing TOTALLY naked on the balcony in front of everyone in the crowded hotel pool below who were all staring and laughing and the boys began cheering and wolf whistling as I struggled to cover myself up with my hands as best I could.
In the end one of the hotel attendants had to come up to my room, let himself in and yank the towel from the other side of the door so I could get back in. I was soooo embarrassed standing face to face with him and absoloutely starkers that I just mumbled something which sounded vaguely like 'thanks' and ran straight for the bathroom!
I spent the rest of the holliday hiding in my room since practically everyone in the hotel had seen me absoloutely starkers - even now it makes me cringe just thinking about it!
