Etiquette and The Chimp Debacle

Okay, I have two etiquette questions here. As a former debutante, I pride myself on being appropriately proper in most circumstances, but I had a moment of etiquette confusion yesterday (Where's Ms. Manners when you need her?)

So, I was at the bus stop and there was a 20-something guy sitting on the bench. I joined him. Then, an elderly lady and another 20-something guy walking with a cane approached the bus stop. Now, the bench only fits two adults comfortably. The kid sitting next to me made no motion to get up. After a minute, I asked him if he wouldn't mind giving his seat to the elderly lady. After looking at me like I was a complete idiot, he offered her the seat. Then, I felt bad for the guy with the cane. I felt like I should offer him the seat, but does a pregnant lady (who was extremely worn out from the day) have to defer to a physically handicapped person? Is pregnancy a handicap? When I wasn't pregnant, I always offered my seats to pregnant ladies.

Oy! Some people stress over the economy or world peace - I, on the other hand, fret for a whole day about bus stop etiquette. Go figure.

Now, about this thing with the New York Post chimpanzee editorial cartoon:
Racist undertones aside, am I the only one that thought it was insensitive and much too soon to be making fun of the chimp attack that almost cost a woman her life and may have cost her the structure of her face? There was nothing remotely funny about that chimp attack, a woman could have died and another woman lost her beloved pet companion. Whatever. I've been really disappointed with the Post lately.
