I just met my best friend for a coffee, to give her her 30th Birthday present before she goes off for a childfree sexfest week in Mauritius with her DH as a 30th Birthday present 
. I got her a pair of very naughty Agent Provocateur, knickers, karma sutra guide, hand cuffs, a feather boa, and this chocolatey lube stuff .I hasten to add this was intended as a joke, I actually got her a day at a spa. She unwrapped a boys top from Zara Kids, a small puzzle and a power ranger action doll thingy.
This means the 4 year old boy whose party my DT'S are at has unwrapped her present. 
. I know for a fact it has been opened as there had been a small mix up with times, and they had to wait 10 minutes to be allowed into the soft play, and so when I was leaving the birthday boy's mum was calling them over to open presents to pass the time.
WHY did I use identical wrapping paper? But more importantly what do I do when I go to fetch them in an hour? Even worse, the whole of their nursery room was invited, plus a few other friends, the majority of which are there. Doubly doubly worse, I was the only mum/nanny to leave, so they will all know.
