There's lots of background story to this but I'll try to keep this short, without dripfeeding.
I live in a quiet cul de sac within an estate. I'm an open person and am friendly with my neighbours. About 4 years ago, a new neighbour moved in with her now DP who was living here with his dc already for many years. She's very friendly and I get along well with her. She and her dp have had problems and she has confided them in me. I tell this part of the story to illustrate that we do get along, although I wouldn't call her a friend. I would never confide in her. She has been pushy in the past (if anyone remembers the steel balls thread, I told how I ended up bringing her daughter to school every day having offered to drive her once).
As I say, we're friendly but...she drives me mad just landing at my doorstep saying "I saw you were home and just thought I'd come over for a chat". I gave many hints that I needed time after work (school) to come back to life before I was capable of adult conversation. I'm absolutely not a confrontational person and find it hard to be rude. Last Thurs, ds had 5 school friends around for a play and I was making dinner for them. The boys had left the front door open and the porch door closed (so you can just tun the handle and walk in). Next thing, my neighbour was in my kitchen saying "Just thought I'd pop over for a cuppa" while I'm standing there cooking. I didn't offer tea and kept cooking, doing lots of "I'm so stressed" noises and eventually she left after about 5 mins. Another time, I had a friend in who was visiting me and my new baby with a present. When I opened the door, I said to X "I actually have someone here, it doesn't suit" and in she comes anyway saying " I'm not staying, I just wanted to ask you about your tiles...." while she walks all the way into my kitchen and greets my friend. There's loads more that has pissed me off but I won't bore you.
My question is this: How do I stop this? What do I say when she just walks into my house? The door is always open when ds is out playing and it would drive me crazy to have to keep answering the door if I was to close it. What do I say when I open the door and I really DON'T want to invite her in??? It's ingrained in me to invite people in when they're at the door and it's really rude not to automatically put the kettle on. But I know I need to be more direct with her. Advice? Anyone any codes for the steel balls shop?
