Sleepwalking is my biggest problem.
Had a few issues over the years and woke up in different beda with different people.

Issue 1 - Staying in the Golden Eagle in Kirkby cos I had a mate up who was a West Ham fan. Went the match and got leathered afterwards which is standard. Went back the hotel. Woke up in the middle.of the night in a different room in bed with some lad. He was fast asleep as was his mate in the twin next to him. No idea how I was able to get in there. Managed to get out without either of them realising. They checked out the next day at the same time and I looked at him thinking "you haven't got a clue what happened last night".

Issue 2 - similar to the above except in a B&B on the Isle of Sheppey, worked there Monday to Friday for about a year. Decided to stay down there on Saturday for a colleagues birthday, it was the day we played Derby away and Stubbs scored.
His time I woke up spooning some random bird with a man the other side. Again very fortunately neither of them woke up. Bizarrely I somehow left a t-shirt in there but didn't dare go back to get it. I went out for some lunch on the Sunday and when I got back it was folded up and put on the end of my bed. The landlady must have known what happened but didn't let on.

Issue 3 - Rented a room off someone I worked with when I did a spell in Shrewsbury. Typical Sunday, out and pissed and woke up Monday morning in the landladys bed, a definite "no" before anyone asks. She did know I was in there but decided to let me stay in the bed as I wasn't causing any harm.

It is a worry whenever I go away anywhere on the lash that it will happen again.
