I went from living at home with mum to living on my own.
No real rules that I follow, I locked the doors at night, maybe thats the main one.
heres what I say.
1) report any missing underwear or clothes from your washing asap. - had a creep jumping fences in my old area and stealing women underwear, I got him on my CCTV and turned out he was wanted over touching a young girl on a bus as well, they finger printed my fence, got an ID and got him.
2) check your gas before you go to bed.
3) CLEAN as you go, trust me here, its better than having to do a huge clean if someone is coming over. Make sure you clean the sinks everyday.
3) If you have a family near by, talk to them & meet them, it can come in handy if you need someone watching over your place.
4) Invite people over a lot, you can feel a little alone when living on your own, plus it tells people in your area that people are always there
