Reply: Had the same plan

In the seventies, I was living in London with a very wild, very beautiful girl from Dublin called Kelly. She loved fighting fucking and drinking (in no particular order). One night we were going round the clubs with a nineteen year old girl from Kerry called Ann. She was also extremely good looking.
When we finally got back to my flat, she was to stay in the spare bed room, I came up with the cunning plan of going to bed as normal, pretending to go to sleep and when Kelly had dozed off, getting up and slipping into bed with Ann next door. Unfortunately that's all I remembered of this plan because as soon as my head touched the pillow, I was asleep.
The next day I got up and leaving Kelly still sleeping, staggered down to the local pub where Ann worked, to get a livener. Ann was very agitated and pulling me aside told me that after we had all gone to bed the previous night, Kelly had appeared and got into bed with her. Don't tell me great minds don't think alike.
