i more salute those that refuse to learn other language. The language your other half punya family use.

You wont be able to achieve this unless u are actively discourage yourself from learning it.

Another golden rule. If your spouse or families tried to nitpick your language skill, tell them to fuck off. It's a passive aggressive way to get submission from u. They drag u to unfamiliar ground and then beat u up with experience, that's exactly what it is. Bullies with low self esteem always do shit like that.
