My mum has used our spare key a couple of times when she's picked DC up from school, so she knows where we keep it. Last week she went shopping locally when I was at work and then let herself in with the spare key to make a cup of tea before heading home (45 minutes away). I don't suppose she was doing it secretly as she'll have known what time I get home and that I would have found her in the house (which is what happened). However she didn't ask me before doing it. I didn't mention anything although I was a bit peeved.
Last night my sister phoned to ask me if she and my mum could meet at my house (again while I'm at work) as they're going to view a house down the road and have half an hour to kill. So could they come round and have a cup of tea? I said I would let them know as I wasn't sure if I was going to be home (sometimes I work from home.) I later sent a text saying that I was going to be at work.
Fastforward to today. They are both outside my house and I get a phonecall asking if they can use the spare key to go in anyway and make a cup of tea before the house viewing. Also my mum has arranged to hand over a piece of furniture to someone she sold it to on eBay!
I don't mind them coming round, but I object to the thinking that my house is an open house with a spare key outside for them to let themselves in whenever they feel like it. AIBU?
