I can totally relate to this thread.
I used to get annoyed,but no more,it's not worth it.
As pp said,haters gonna hate!
My wise dd says,if you haven't got anything nice to say,don't say anything at all.
I shall list a few of the comments-
Why?
You must have more money than sense!
You must be rich!
You should've paid off your mortgage early instead!
you don't need to go there!
You're going there,again?
I wouldn't spend THAT amount of money on my whole vacation,never mind just for tickets!
You should spend money on-new house,New car,home decorating,etc
And so it continues. I tend now to only mention our trips to those who "get it".
The negatives far outweigh the positive comments,but they can all do as they please,and we'll continue to do what makes us happy.
