<human>: Can you provide a brief overview of the text?

Last week I was flying back home and ended up in the middle seat. When I sat down this lady walks by and sits next to me. Worth mentioning is that she had one of the biggest, fattest wedding rings I have seen probably ever. First thing she does is buckles herself then pushes up the divider thing between us, turns to me and says like this is the first time she is flying by herself and she is not uptight so if I wanted to I can lean on her and all she will do is just lean back. 

When we were going up in the air she started holding on to my arm pretty tight and rubbing it..that continued pretty much every time there was any sort of turbulence. One time she said "I must freak you out by doing this", then she put her left hand on my leg and held on to it. I said "oh no it's fine". I really didn't know what else to say. Honestly I started liking it and actually got a semi in my jeans which I think she saw. 

This continued on until the plane landed at which point she started acting like I was someone she saw for the first time, grabbed her bags and walked off without saying anything.

Why do women do stuff like this reddit!!??
<bot>: Lady was all over me during plane flight, then acted like I don't exist as soon as plane landed. Why do women do this stuff?
