I'm going to tell my husband to stop referring to my sister as 'babe'
Why don't you want your husband addressing your sister as babe?
It's gross. He said it in front of six people the other day.
you're right, you should tell your husband not to call your sister babe if you're uncomfortable. I'm sure he'll listen to you.
Yeah, I probably will. Thank you.
Your husband is probably doing that subconsciously and is not aware. When you let him know, he'll probably stop right away. Suggest another nickname he could call her if he wants to address her in that manner.
