I wish I'd known that living alone would change me in good ways - the light flooding into the big bedroom on weekend mornings when I could make coffee and get straight back into bed - no peace like it. No one coming round, long days of aloneness stretching out if I wanted them.
I wish I'd known how I would lose my tolerance for stupid men dropping round wanting to stay and ruin my evening, and that I would learn really quickly how to stand up, stretch and say 'Weeelll!! It was LOVELY of you to pop round...' and watch them mirror my behaviour, and then I could usher them out. I learn very quickly how to get rid of people if necessary.
I also wish I had known how much I would enjoy living alone, especially when I got a cat who waited for me every night.
I also wish I had known that buying a dehumidifier would help with the black spots of damp in the bedrooms in winter, I will never be without a dehumidifier now.
But I second those saying, hide spare keys. One day off sick, in PJs, let the door close - ninety quid later.....lesson learned.
Congratulations and enjoy xxx
