I live on quite a quiet road, we dont have net curtains or blinds, just curtains and as the odd person walks past they sometimes look in. I dont mind this. I look into peoples windows too sometimes as I walk past though I try not to. 
However one of my aquaintances/friends recently became very friendly with my next door neighbour. We are all the same age and have children in the same class. My aquaintance/friend is one who I like but I dont think we have too much in common so we havent been to each others houses or anything, just playdates out with others or chatting at school things. I like her but she is very nosy and seems to know EVERYONE.
Now she is getting very friendly with my neighbour and she comes over quite often, this is fine except when she comes to see my neighbour she also stands right in front of my front window (its a bay) and stares in waving at us all and trying to talk to us.
This I find very rude!!! She does not need to stare into my window - my neighbour and I share a path to our doors (terraces) but when knocking on my neighbours door you do not need to look into my house. She actually steps up and walks around the side of the bay to stare in at me.
I told my neighbour and she said she had told this her that we dont normally do that to each other but she is still doing it.
Am I being really stuffy? Am I asking for it having no nets or blinds?
Last time I saw her pull up in the car I told my children not to engage her at the window as I dont like it. Once again on the way out she steps up and peers into my window! I was in the hallway hoovering - I could see her but she couldnt see me. She was having a right nosey!!! My kids ran out of the room and later on she msg me and said she had "stopped" by but the kids ran off and then she did a sad face. I didnt respond.
Is this normal??? Should I just tell her not to be so nosy. If she wants me for some reason she could just knock on my door!
Am going out but will check later to see if IABU about finding this very rude.
I hope not!
