Why can't aunt and aunt get along?

You can't just listen to what others say. Gossip is not a good thing. I may say something to your sister-in-law. It's not worth listening to other people's gossip. Now everything is believed through the grapevine. If you have a chance to discuss it with your sister-in-law, you will definitely make up. Convince yourself first, don't believe the rumors. Be honest with others.
