I have a few people in my life (1 friend and my parents, altho Mum is getting better) who call up and let the phone ring and ring for ages. I have a small baby and am often upstairs in the shower or baby napping, and they let it ring and ring. The friend even rings repeatedly every 3 mins or so till i answer. When i do they are indignant if i am annoyed and say something, and I have had responses such as 'fuck you then, i'll never call if i'm such an inconvenience' and then phone slam.
If i call someone and they don't answer within 4-6 rings i hang up.
So aibu to think it's rude to let the phone ring for ages? And can you buy house phones you can mute? I keep my mobile on silent because of them, but they just ring the house phone. It has never once been important btw.
I have spoken to these people numerous times and they are adamant i am being weird.
