AS, I have found that in me as well. I was 25 when I got married , my husband and I used to talk about the older people not wanting to hear anybody else's opinion and how wrong they were.
Well, look whose got to that point!
I wish there was a way to feel more open, maybe being aware of it, would make you feel like listening at least to the 3 fisrt words somebody has to say, lol.
Ohh well, I tried!
