Ok now listen, I know it can get hot on an airplane. Depending on who you're traveling with, it can be a lot. Especially if you got kids. And well this mom probably just couldn't take it anymore.
And thank GOD this was before takeoff cause I thought it was while in the air when I first read this and was like oh my gosh no! But the real question is, would your mom do this? Cause those hot flashes are real!
