So today my wife had to go to work . My mom got so pissy because we didn't get to go where she wanted because we had to stay in town so we could pick

Up my wife from her job. She's a substude teacher. It was her first day. And my mom couldn't even be happy for her . She didn't even ask how her day went. Instead she made her feel like shit.and I'm so mad at my mom for acting this way towards her on her first day. Bad enough she felt like she wasn't good enough. I felt like saying something to my mom like how dare u but I didn't . I just don't know what to say or think.
