Who should take the seat?

I could sit on the seat and the sexy lady could sit on my lap. That is the best use of the space. The kid can sit on the floor. We should not assume that the other two need to sit they may prefer standing. Of course the ideal arrangement is that we all agree to share the seat 20% of the time each. I could then demonstrate my ciompassionate qualities to the sexy girl and hopefully make a date with her... In my dreams!

I'd only have confusion with two. Either the pregnant woman or the old woman. But maybe if the pregnant woman was very much pregnant already (like 8-9months) then she should get the seat since being pregnant isn't easy and it really takes toll on your back and legs. On the other hand, the old woman is my second choice if the pregnant woman could still manage, it's quite dangerous for an old woman to stand. Perhaps they should all wait for another bus to come. =)
