YANBU, and I don't think it hurts any of us to be a bit more grateful, if we've been dealt a decent hand.
It's not about being 'lucky', it's just about appreciating what you have.
DH caught a flight yesterday, and watched a movie on it, called Manchester By the Sea, or something.
I got an email from him when he landed telling me he'd just watched it. It was really good, but really depressing.
A couple lost their children in a house fire, and it detailed the fall out for them, afterwards.
When he landed, he just wanted to let me know how much he loved us and was grateful for us (and he also wanted me to make sure the house was all safe).
I think this sometimes to myself, but I don't tell him often enough, and I don't really let myself dwell on it, to truly appreciate it. I should.
In other words, I get what hickory* is saying.
