I do think that we all act immature with time. It is our human nature to not always be perfect, to be young at heart with times, and yes, to get upset with times. I know, and I can honestly say that I am guilty.

You have given such a long list of what we, the elderly, can learn from the young that I now feel all guilty.
I should give my stepson more credit. (•ิ‿•ิ)

Good luck!
