One year in but a newbie

[Lifes Twists]

Not sure how to handle tonight. I got a call from my daughters asking what I was having for dinner. They did not know what to do for dinner. Seems there mother left for a date without either completing dinner or really telling them how to finish it. While they were over I asked them if they needed help with homework. Youngest said she needed help with math. Youngest asked me if we could move south. I asked, what about your mother. Daughter said mom can stay here. I asked you would want to leave her alone and daughter responded that she is being annoying in reference to mom. I went back with daughters to apartment to help youngest with homework. Wife called youngest while I was there and asked what happened. I could hear the conversation as daughter was sitting next to me at the table working on homework. Daughter told her they did not know what to do with dinner so called me. Wife then asked her if I was there. daughter said yes, wife asked her why I was there in a way that I could tell she wanted to know if I forced my way in or was snooping. Daughter told her that she needed help with math and I was helping her. Wife then text me later and asked if girls ate the dinner she had started. I replied no and that I had put it in the frig so it would not go bad.

The girls are both in high school. I can understand needing help with the homework, but I think they should have been able to handle the dinner.

I am wondering if this was a set up to expose their mothers dating to me? Is it possible they are tired of covering for her? Should I read anything into my youngest saying her mother is acting annoying? Do I say anything now that the elephant is in the room? Since she is dating, should I?
