I know I have a lot of male readers so I wanted to help you guys out.
If your wife/girlfriend/significant other gets a hair cut, and you don’t say anything about it, she is going to think you hate it. As in, ‘if you can’t think of anything nice to say, don’t say anything at all.’ Especially if her hair is a completely different color or considerably shorter. It might actually be better to say you liked it the old way better, but she still looks nice than nothing at all. Or she might be silently freaking out until she starts crying for what would appear to be no reason. Even if you liked her new hair the whole time.
Not that I would ever do anything like that. I’m just sayin’.
This might save you some grief in the future.
You are welcome.
