I do like my own company. I lived alone for 7 years. I was never "lonely" though. I had a brilliant time going where I wanted, doing what I wanted and generally pleasing myself. If I had the need for company I could always call on family or friends, but by and large I was happy to please myself. Used to pop into town to some nice restaurants to eat, or for a quick meal at the local pub. Used to meet friends for a week on holiday and then go off touring on my own for a further week.
I live alone again now. I've loved it. The fiance is the same. So it's going to be a massive shock when we move in together - particularly as we both work from home. It's going to be a devil of a job finding a house with TWO bedrooms with ensuites, TWO offices, TWO sitting rooms, TWO kitchens ;)
