So I have a friend, we used to meet almost every other weekend before lockdown. Since the lockdown happened, shes got into a habit of just turning up at my door. She always used to text me if shes on her way from some where and is passing through my house. Now, she just turns up! She turned up 4 weeks into the lockdown and barged in. Without waiting for an invite. I was shocked! Made herself comfortable and said that she was low risk as she hasnt been anywhere else! I was too shocked in the beginnign and kept tellign her I ahve work to do but she ignored my hints. After having her coffee( she demanded) and an hour of her talking at me while I tried to look busy she left. She knocked on my door again, on a week day, I was working and this time I blocked her from entering my house. I said I was on a call and couldn't talk. She knocked on my door again a few days ago, she said I was in her bubble. Didnt give a choice to see if I already had someone in my bubble. I have a best friend who lives close by in my bubble! I made an excuse and said I was on the phone with work and couldnt spend time with her. She was trying to barge into my house and I had to block her again. Shes not getting any hints!!! I have informed her my son is v v nervous about CV19 and is not wanting people coming over. He lives with me so I need to be respectful of his wishes as well. But she ignores everything!! What do I do!! How do I tell her she cant just barge in?
