[Light-hearted]
I will caveat this by saying that I do love my mother dearly but she drives me round the absolute bend with this. Any time we talk:
Her: "I was chatting to Anne, you know Anne from next door?"
Me (thinking): Yes, I know Anne, I only lived next door to her for 15 years too and she only babysat us many many times.
Mum: "Do you remember Betty, from Closest town?"
Me (thinking): Yes, I know Betty, she's only been your best friend and like a second mother to me for as long as I can remember and I saw her daughter last Tuesday as you well know.
Meeting someone on the street with her: "Oh Lockheart you know Sue from down the road." Yes of course I bloody know her, she's only lived there 20 years and we saw her last fecking week. She came over for coffee! We were both there!!.
Mum: "Did you know Cathy has a new car? You know, Cathy your cousin?" YES I KNOW WHO MY FUCKING COUSIN IS FOR CHRISTS SAKE
The above examples have unique names in our social circles. We don't know a million people all called Linda, for example, where differentiation might be justified
That I could understand.
Just why?? I'm honestly awaiting the phone call which goes "Hello love, it's your mother, you know, the one who birthed and raised you".
My only theory is that either she has the memory of a goldfish or she thinks that I do 
Please tell me other people's mother's do this and it's not a torture she's dreamed up just got me?
