What would you do if your best friend bought you a book about of all things Menopause?

I don't know how old you are, but it sounds like you have a lot of issues. Her daughter's feeding had nothing to do with you-the baby was hungry and it was just women, so what is the big deal. If your friend is old enough to be a grandmother, she may be going through menopause, some women do in their 40s and she found this great book and wanted to share it with her dear friend. I'm sure she did not intend to insult you, it was just the way you decided to treat it. The rest of us do and have discussed menopause with our friends and make jokes about it. Stop with the denial and don't ruin your friendships.
