So today my period started today and I don't know if it's a mental thing but once my period starts, then I would blame my mood on my period i know lol childish. But today I was in office hours ( junior in high school ) because unit exams are coming up this week and I have two to study for tomorrow so I stopped by to make sure I understand everything properly and so my best friend said she would wait in the library. When I was finished , it was 4:30 but was very dark outside because it's autumn and it looks like it's 10pm when it's just 4pm.. I hate it. But when I was finished, I saw her in the library talking to her friends and so I went up to her and told her lets go because it's dark and my belly is hurting me and where I live it's dangerous. And I guess I was wining that I was ready to leave but she wasn't moving and so she got mad and telling me that I was giving her an attitude (which I wasn't ) and she stormed off and left me to walk home my myself. Then it started raining 😓

Please tell me who was in the wrong or who has the right to get mad! HELP! She isn't talking to me right now but I'm just going to let nature play its course and study

Note: we just got back into talking again because over the weekend, we had an argument but we started talking again on Sunday.
