I figred that it wasn't an important call. I don't think that it was a spam call, because the spam calls I get don't repeat each other, plus number itself has a pattern that makes it easy to remember for humans. So what's left is to figure that whether someone who called was important or not. So I went through and thought about it, and it couldn't be from military because it was too late of a call, I think if it would be them then they would call earlier in the day, between 9 A.M and 1 P.M. It wasn't from a job hunting because it was Saturday and it's was also a saint Nicolas day. My former classmates from uni would try to contact me on social media first and then call, but I saw no message from them there. There is one relative that sits in jail right now and he sometimes likes to call my mom, but even if that's the call from him, I wouldn't want to respond it anyway. If it was from staff from uni which I already finished, they would try to contact me through my classmates. If someone wanted to just greet me with saint Nicolas day, then it's not important, even if they got present for me. If someone wanted to invite me to party, I would refuse anyway. If it was a prank call from my classmates from school, then fuck them.
