Not talking about vaccines! Don’t worry!

Recently my husbands brother tested positive for covid. He lives with his parents.

The day before he tested positive, my husband talked to his mom just in passing in the backyard when she was dropping off the lawnmower she was borrowing. They stood way more than 6 feet apart and they talked for less than 10 minutes.

My sister is treating me and my husband like we’re sick and won’t have anything to do with us until we hear if his mom has tested positive or not.

I was supposed to visit her and my mom tomorrow and she said that she didn’t feel comfortable until my mother in law and husband have tested negative.

I’ve told her multiple times that he saw his mom for 10 minutes outside and they’re both double vaxxed. (I understand you can still get covid though)

I understand her worry, but she’s being very rude about it.

My husbands brother has asthma and is high risk so we’re pretty worried about him and his parents.

Who is in the wrong here?
