We had a big play park installed in part of our back garden a while ago. I have a few local mums I have over for play dates quite a lot and they were all saying it's brilliant and better than the village park (the village park is awful which is why we initially decided to get our own) I said to them that as our house is empty most weekdays that they can feel free to use it when we're at work just let themselves in no need to ask.
Obviously they are only doing what I said they could, I don't think for a second they are being unreasonable. I've not been well this week and fell asleep on the sofa this morning and woke up hearing something and could see one of them out the french doors sat on the decking and her kids playing on the park. I felt really embarrassed having to stand up and wanted to just hide until she was gone as I didn't feel well or very social. I did pop out to say hi but got stuck in conversation and felt too awkward to ask her to go as I didn't feel well. It happened the other day too with a different friend and I just wanted to go put my washing out on the line but due to feeling unwell and looking rough I didn't want her to see me and she wasn't to know I was there so I just avoided doors and windows. Her toddler fell asleep in her buggy and she sat there on my garden furniture on her phone for a couple of hours and I just felt like I was having to hide in my own house
How do I retract an offer like this? I genuinely don't mind them using it outside of play dates but preferably only when I'm not home and feel obligated to go say hi, chat and offer coffee etc. AIBU if I ask if they could text first after all? I feel rude as is previously said just turn up and I don't want them to think I have a problem having to see them and get offended
