Should I entertain my aunt and uncle?

If you don't spend your mother-in-law's money, you have no obligation to entertain them. Let them bring their own drinks and meals. Aunt went back to her mother's house to see that her mother didn't bring a present.

If the host is a mother-in-law, then help her mother-in-law, honor the elderly, help and leave it alone.

If you have a good relationship with them and want to have a party from the heart, entertain them.

For someone like you, it's obviously not from the heart. If you force yourself, you'd better make it clear.

And get the support of her husband, and explain your feelings and reasons clearly.

Housework, honesty and integrity, let alone others.

Only mutual understanding and mutual encouragement is the best solution.

Don't fight, it will only leave the other side with inner scars.
