@bytheMoonlight - I was quick pregnant and iirc I was traveling into London to go to a high school reunion, I didn't want to go but my sister had arranged it so I had promised to go.
I had been in a hot car for 6 hours already that morning (traveling back with DP from our last holiday as a couple) and I had enough time to go home, shower and throw on some makeup and clean clothes and DP dropped me off at the station, which I then had an hour on the train getting into London - I know it's a bit of a long back story, but I think you need to see how fed up with traveling I was at this point.
Anyway - so I finally get on the tube, and there are no seats, not a problem I think, I'll just stand, but it was one of those weeks last summer that was so hot, and I started to feel very light headed. There was a woman sitting in the priority seat nearest me, so I said to her, "would you mind if I sat down for just 5 minutes? I'm not feeling to well and I'm pregnant" She then responds that my only problem is that I'm too fat and refuses to move. So I sat on her, for the entire rest of the tube journey, she started shouting "get off me, get off me!" but I was so pissed off at her, and so hot and bothered that I think she missed her stop, because I didn't move until I got to my stop. The rest of the passengers found thsi really quite funny, and I do now, but at the time I was just fuming.
I should add, I'm normally a very quite and reserved person and wouldn't have dreamt of doing this.
