What should I do.??!!!?

Okay so I want to now what I should do about my mom. So okay my dad is blind and my aunt and her husband are letting us live with them. Cause if they didn't we would be homeless but ya anyways so my aunts mother in law is here to visit and she is so sweet since I don't have a grandma cause she passed away before I could meet her. My aunts mother in law is acting like a grandma for me and she is so nice to my mom she asks my mom something and it always seems like my mom is being rude and it's not cool because they are doing all these things for us and my mom doesn't realize this
