Another bus question

[B Dids]

I'm on the bus. I'm a large dude- so I typically sit in the bench seats on the back because if the bus is crowded, it's just not fun for anybody if some poor bastard has to sit next to me.

So, this younger couple, kinda stonery, unkept but not gross looking [censored] get on the bus, and end up sitting down next to me. Instantly the guy asks the girl to sit in his lap. Pretty quickly they're kinda kissing, making out a little bit, doing goofy couple things that are crossing a line on the bus. She's got him straddled at times, tickle fighting, more than just a slight kiss or something.

Now this doesn't gross me out much. To be honest, it's a slight turn on, as the chick is pretty cute. That said, I feel a little affronted that they're doing something which is in some way disrepsectful to me by most standards, and I feel a slight sense of obligation to give them their privacy, there's empty seats on the bus, and who am I to get in the way of young love?

However, a bigger part of me says "[censored] this, this is my seat, I sit in this seat on the bus almost every day, and I'm not moving 'cause these kids can't hold out for 20 minutes", also, I think part of what they're doing is just trying to get a reaction out of me, and I don't really want to gratify that.

So I ended up just sitting, mostly trying to ignore them. I sort of feel like the right move was moving, but pride and ego are silly things.
