I have a really good friend who I would never want to upset or offend. She lives around the corner from me and recently has started to call round to my house without ringing me or texting me to see if it's convenient. This happens maybe three or four times a week. I work full time and have a five year old and I'm a single parent so I really value evenings by myself. I know this sounds quite selfish but I really would appreciate a quick call or text to see if I want company before friends call round. It has even got to the point that if she notices my car is not outside my house I get a text along the lines of "where are you then???" from her. I really don't want to upset her but I am getting a bit fed up of pretending I have got plans every evening so she doesn't just turn up at my house.
