Is AUTHOR wrong in the post ? POST : Background: My family is Jewish but not super religious. Every year, during the winter holidays, we have a Hanukkah party with my family and another family. Lately, I've hosted since I moved to a new apartment that's decently sized (New York, so not actually that big).

Story: Every single year, the party starts around 4-5 pm. However, this lady, we'll call her M (she's a part of the other family), always shows up an 1-2 hours before the start time. I wouldn't have such a problem with this if all she wanted to do was hang out in the living room, but M spends her time standing around in the kitchen and "helping". Basically, she stands around telling me how to cook certain things and I find it quite annoying, especially because I need to cook multiple things before the other guests arrive, and I really don't need the added stress.

My plan is that next Hanukkah party, when she shows up, I simply don't open the door. That way, she'll get the message that she's not welcome before the party actually starts. 

My mom (the only person that I've proposed to his plan to) thinks that I'm an asshole because M it's an old lady and it would be cruel to leave her out in the New York cold. 

TL;DR: I want to ignore an old lady when she comes to the door long before the party starts so that she gets the message that she's not welcome that early.
