For this one it's the "celeb" that was highly embarrassed not me...
One of DSIS's school friends married a famous sports personality. DSIS went to their wedding years ago, had photo in Hello etc etc. I don't remember the friend and never met her as far as I recall.
Years later DSIS is getting married and, naturally, invites friend and famous husband who accept. Cue much excitement from family including DM who is beside herself clutching autograph book (which is embarrassing in itself
)
I had DS and had been through a few surgeries recently so opted out of being Matron of Honour/Bridesmaid etc, not a problem. DSIS says she will put us on the table with celeb. All fine.
I had new outfit/hair and makeup done for the wedding, look half decent considering.
So we're at the venue and whispers go round that they've arrived. We're cool and hanging back. Eventually they approach our direction, friend extends her hand and utters the, now immortal, words "Hello, you must be the blushing brides MOTHER"
Well I was the one doing the blushing but quickly pulled myself together, stood tall and responded "No. I am the bride's sister. In fact, her younger sister. BY FIVE YEARS. I'll see you at the reception". Then promptly turned on my heel, found the toilets and burst into tears.
The reception was awkward interesting. My "D"M found it hilarious.
Celeb friend, if you're reading, I still haven't forgiven you.
