Just remembered another one. This was a new baby gift after DS was born.
A friend wasn't able to come see DS until a few weeks after he was born, but she rang up, and excitedly told me that she'd got DS lots of super brilliant wonderful presents, I'd really love them, etc. All super enthusiastic.
So, after all the build up from my friend, I wasn't sure what she'd got DS, but was expecting it to be something half decent. She then came round, and presented me with a bag of random crap from a car boot sale - including bobbly stained babygrows (both pink and blue), chewed board books that had been scribbled on by the previous owner, and a set of bottles and teats that had apparently only been used by one other baby. And she happily told me about what a bargain it had all been, and listed the prices she'd paid. Friend is very well off BTW, and has never before, or since, given us presents from a car boot sale.
I''ve always been happy for DS to get good quality second hand stuff - but this really wasn't good quality.
And I still wonder why she didn't just say "I've picked up some stuff for baby Purple from the car boot sale", instead of building it up as if it was going to be a good present

I really don't think I'd have minded all that much if she'd been open about the car boot thing from the start.
