Even though I get so angry and upset at the time, I normally calm down and always try to believe the person never meant to hurt me (and yes even my MIL)..

As you say, we all view things differently. Different cultures, generations and beliefs can make us interpret things in a way they weren't intended.

I also know that I can be too lenient in my thinking that it wasn't meant that way, and not say anything, that I leave myself open for the same cycle again..
