AITA for getting upset because someone called instead of sending a clear text then got angry at me when I explained my point of view?

I know the title is confusing so I’ll explain in detail.

For starters, my sister and have a difficult relationship and we see and do things very differently. We’re currently trying to work on our relationship but she has a superiority complex and I’m too rigid.

So around 1pm I noticed that I had one missed phone call from my sister at 12:30. I’ll admit that my phone is almost always on silent but at that time I was on an improvised meeting with coworkers during lunch break so I wouldn’t have picked up even if the phone had rung.

So as I said, I saw I had missed the call at 1pm. It was one call, no messages. I called back right away twice but she didn’t pick up. I then sent a text that said "?". No reply. I said to myself that it was probably nothing but was a bit rattled. One random missed call with no follow up text felt ominous to me especially since things at home are a mess and our father is gravely ill… It was also raining heavily so dark scenarios played in my mind.

I’ll add that I didn’t have internet connection on my phone so when I got home, I checked my phone to see if she’d texted me on messenger and there was a missed call around the same time as the other one. So she must’ve tried me on both phone and messenger. I sent the same "?" message on messenger too and went to change. Then I got a message on messenger that said "are you home?" To which I replied "yes". I was already getting upset with her round about way of communicating and didn’t feel like sending a longer reply. She replies with a voice message ask me to remove a few of her clothes that were air drying and put them inside. I didn’t reply but did as I was asked.

I was so upset. It was something so small and time sensitive because of the rain so why couldn’t she have just texted "hi, if you’re home could you take my clothes inside"? Surely that’s simpler and to the point instead of calling, then waiting for my reply, then asking if I were home, then asking me for this favor. Wtf is wrong with her???

She got home about an hour later and we ran into each other in the kitchen and I asked her why couldn’t she have just texted and she replied testily "why didn’t reply?" As if I had nothing better to do with my time than be ony phone all day. Her reaction made me more upset and I insisted that it woud’ve been simpler to just tell me straight away via a message. Then she said I should’ve called her back but I said that I did call her back and she was the one who didn’t pick up. Then when Insisted that a text was more practical she said " adults don’t text, they call" WTF IS THAT???? And then she went and called me crazy.

I’m so angry and I get that I’m overreacting but I feel so hurt. She calls, makes me worry, drags the request, blames me for not picking up, accuses me of not calling back, belittles me since I’m younger and then calls me crazy.

So reddit, am I the asshole?
