My mum is driving me round the twist with her bleeding mobile phone behaviour. We bicker over it a fair bit, including last night. She says I'm being a priss. I say she's being rude. If I give you some examples, can the MN jury clear this one up please? Ta 
*Gets 'phone out in sitting room, whilst DH, DS and I are watching Eggheads. Proceeds to dial her friend and speak in unhushed tones. When she is having problems hearing her friend, she will pull a wincey face at me and gesture for me to turn the telly down 
*Sat at the dinner table after I have cooked, she'll hear that her phone has a message alert. She will leave the table to read the message, sometimes she will even ring the sender back, at the table, using one hand to hold the phone, the other hand to try and eat.
*There have been occasions (Mother's Day for example) where MIL has been present. MIL and my mum don't see each other often. MIL will be talking to mum and mum will read a received text message, in the middle of conversation.
There are more. It's the kind of behaviour that I would expect from a fourteen year old, not a fifty four year old granny. I really shouldn't have to be remonstrating with my mother over politeness wrt mobile phones, should I? Or am I being a stuffy cow?
