Luckily I'm a very homely person anyway. Even at university I wasn't one of the party animals. And my big drinking days were over long ago. I'm at my happiest when at home with my family so I'm sure I will love my life.
Its the spontaneity that I will miss. Being able to leave the house and jump in the car with just my keys and mobile, being able to go out for dinner at the drop of a hat, being able to have sex without worrying who might hear us, things like that, being able to go shopping in town and pop into any shop I like without worrying whether the buggy will even get through the door, let alone down the aisles. Things like that.
I also worry about money, but thats too bigger topic to go into.
