I know exactly what you mean.
It is a tradition at Christmas that the missus does stockings for our two kids that they open Christmas morning before opening their presents from under the tree. Now this tradition includes their wives and our grandchildren too.
This started off years ago with just a few bits and bobs to keep them amused when they woke up in the morning as was left by the side of their beds. That meant mum and dad did not have to get up at silly o’clock with them. Well that was the plan anyway.
Now the missus tends to spend about £200 on each stocking plus whatever main presents she buys them all as well.
When I moan how much she spends she just says "well you get one too don't you" Bless her
