and I had to hide upstairs in my office
I wasn't allowed! I always have the excuse of "I can't speak to them" to get out of some things :)
where they had a lady come out and do a Spa in our living room...
This sounds great for that age. Did they enjoy it?
Surprisingly they really enjoyed it. Though I was not there for that part as it would be weird, so my wife managed that part. But I could hear all the excitement and they played music which was drowned out by all the fun they were having.
