Is AUTHOR wrong in the post ? POST : A bit of quick backstory. I am in high school and my mum is in late 50's. She picks me up from school but once a week, she goes shopping before she comes and picks me up. When we get home, I help her to carry all (Or most) of the shopping upstairs to the kitchen for her.

This time however, instead of quickly dumping my school bag and other things inside and going back outside to help, I walked inside and put my stuff away (maybe took half a minute). When I was done, I heard my mum coming to the door with some shopping bags, so I waited at the door to take them from her so I could carry them upstairs. When I asked to carry them however, she simply ignored me and walked straight upstairs. I asked why she ignored me and she went on about how she waited outside for me to get the bags but I wasn't there to take the heavy ones and then called me ungrateful for not taking them. 

And the bags she took in were the heavy ones, and left the lightest ones in the car (Which I carried in straight after).

And when I came in with the rest of the bags, she was still angry and said I was on my phone or something like that.

Am I the asshole here? She always gets angry about little things like these and if thing aren't done her way. I don't really know what to do at this point.
