Without a doubt, opening up to others as I get older seems weirder than it used to. Then again, the older I get, the wiser and more emotionally intelligent I get. So when I open up I'm more secure in myself and I'm less vulnerable. Both are still new feelings for me so that may contribute to the weirdness.
I definitely don't tolerate certain behaviors from anyone anymore either. In the past, I would politely tolerate being interrupted. Now, if I am interrupted I call people out and ask if they interrupted because what I'm saying is unimportant to them. If people keep talking after I say that, I walk away. Confidence and self esteem are also fairly new to me, so that could be a factor too..
Once I get used to this stronger, healthier, happier version of me, I think opening up may be less weird.
