A friend of mine's parents took a grandparents class at the local hospital and said it was great--they had a lot of fun and got a refresher, learned the updated stuff, etc. I suggested the same class to my mom and she got really, really upset. Called me back crying and said she's never been so insulted in her entire life and will not be taking a class. Insisted that she knows how to take care of a baby and then asked if my SIL asked HER mom to take one and is so offended that I'd even suggest it.
Ugh. Did not expect that.
