A colleague has just brought in dozens and dozens of photographs that she has printed off of her sister's wedding. I said politely 'Oh can I have a look', meaning I'd like to see a few of the pictures, comment on how lovely the dress was etc. Twenty minutes later I was still standing there being shown photo after photo, some of them identical to each other, trying to think of an excuse to get away.
Someone else did this recently with baby photos. Reams and reams of the baby in the same outfit, looking exactly the same in most of them while I tried to think of 500 different ways to say 'oh, isn't he cute'.
If I'm showing photos around I pick a few of the best ones and don't bore people with the whole lot of them.
AIBU to think that unless its a close family member who's just as interested in the wedding/baby as you are, just hand around a few photos and put the rest away?
