Is it normal that i tend to please whoever is in front of me?

Here's something that happened today: my mom asked me if I would have liked to go see a Greek play with my aunt. She was looking at me like she was trying to make fun of me. I initially wanted to say yes, because I've never seen a Greek play before, but my mother's attitude made me hesitate. When she saw that I wasn't answering she said that she didn't think that would be to exciting, so I quickly said that I didn't know this specific play an that I would do some research. After a minute I told her that the author of it was boring (that's a lie, I still have to study both the play and the author at school). So she told my aunt that I said it was boring and didn't want to go. I did this because I didn't want my mother to think I was being weird and because I thought that my aunt invited me there just to make me have fun, even if she found it boring.
Then my aunt called me and told me that she wanted to go because she has never seen a Greek play before and though that could be interesting and she asked me to tag along because neither her husband or her five years old kid (rightfully so) didn't want to go. I felt like shit, I told her I wanted to go too and that I said no in the beginning just because I thought she was doing it just for me.
My mother heard that conversation. She asked me why I changed my answer, why I said I wanted to go if I said it was boring first and that it would be just a waste of money. She then told me I do weir stuff. Is it normal that I did all of this hussle just because I didn't want to show my mom I liked something she doesn't?
I find it funny that the whole point of my behaviour was to show my mother I'm normal and that I think like her, but in the end I still managed to be called weird.
