Yesterday I was flying and a young lady was next to me in the middle seat. I never put my arm on the middle armrest. I find that it causes too much drama, but I will sit normally which means im next to it. The young lady thought it was ok to extend her elbow into my waist.. I had sat first then she came. Completely jumped over my legs to get to her seat (didn’t give me a chance to get up lol) so we were already on one. 1/6
