To the schmuck on the 19 downtown yesterday around 5pm, who felt it was more important that he sit next to his girlfriend than the lady who was on the bus before him use the seat: what the fuck is wrong with you? She was there first, why should she have to stand so you could sit next to your girlfriend? If you were 14 I might have not given you a dirty look and said "really?" but you're clearly in your 30s and should not only know better, but should be happy to give your seat up for a woman (or man!) older than you. Putting your arm around your girlfriend for the next several stops didn't make any of us think you were romantic or sensitive. Asking someone to give up his or her seat for your able-bodied ass on a full bus is a Class-A dick move.
Your girlfriend is clearly a very lucky gal.
