This may just be my issue but interested to hear if anyone else feels the same.
I have a good friend who I am close to. We have boys of a similar age and went through all the excitement and anxiety of pregnancy, labour, birth and tiny babies together [I actually supported her through the early stages before she went in to hospital with her DH]. Our boys are now good friends and we are in and out of each others houses frequently.
My friend and I are also part of a wider social circle of mums in the local area.
This is the social circle we share together. Obviously we have other friends from other parts of our lives, from college and work for example.
However my friend regularly names ones of the other Mums in our social group as her "best friend". This Mum [lets call her Ann] she has known for slightly longer than the rest of us and they are very close but Ann has since moved away and they no longer see each other as frequently. But my friend will say to all of us "My best friend Ann and I went to see this play" for example.
It just makes me feel a bit second best to hear Ann referred to as the "best friend". I know my friend is entitled to feel this way but wonder if it is really that tactful to say, as obviously it makes some people [me!] feel unvalued.
As I said, this may just be me. I was always a bit insecure in my friendships as a child [lacked self-esteem and often felt on the outside] and I guess this talk of best friends brings all this up. I feel yet again as if I don't measure up somehow and am not good enough to be her best friend 
But I also feel it is a little tactless to keep rubbing it in our faces that we are just friends but that Ann is a "best friend" and is more special somehow.
AIBU?
[And Merry Christmas to you all
