I have a twin sister and we are opposite sides of the same coin through and through. We both have our own beliefs, morals, principles, preferences.... everything. I try, God knows I try to understand her and majority of the time I rationalize everything about her I don’t understand or force myself to look at it from her perspective but I don’t get this one thing.

She doesn’t like it when I ask her how much something cost. I don’t mean in the “how much did that bag cost” way either.

Earlier she went to the liquor store to pick up something for herself and I. I wasn’t sure what I wanted to drink as I can’t remember the last time I had a drink. The store is small so not a lot of options either. There’s a rum I like from my home country and before I even said I wanted it I asked her what the price of it was. When she said she didn’t know I asked if she could ask someone. She did after much protest. The bottle in my opinion was too small for the price. I’ve bought it cheaper at that size before. So I’m looking at other types and asking her the prices for comparison. I’m on FaceTime during this. She walks out the store around the building where no one could hear us and starts asking me “why do you do this” I’m respond “do what?” She said “ask for the prices.” I’m like huh? She’s goes “it’s not like you’re going to be paying me back for it so the price shouldn’t matter”. * This is messed up because she has been working and I haven’t because I’m a full time student, studying for my mcats which she encouraged me to do.

My response to her was, I am not comfortable spending a certain amount of money on something that isn’t worth it, more so having someone else spend that money on me. If prices don’t matter to her (which she admitted to) that’s fine but I’m not wired that way. I am money conscientious. She goes on to say that what I did/do embarrasses her and I’m selfish for ignoring her feelings and choosing to act in a way I know embarrasses her. Then she decides she’s picking the bottle for me and not taking me back into the store because she can’t trust me not to embarass her. I don’t protest because it’s her money she can and will do whatever she wants and I will just be humble take what you give me.

In my mind normal people ask for prices before they let other people buy things for them. How is it embarrassing. Does she think someone is going to think she doesn’t have money if God forbid she ask for a price? I told her this and she said I could psychoanalyze her later with my degree🙄.

Am I wrong? What am I missing here?

Sorry this rant was so long.
