Explaining old age without offending anyone isn't as easy as you'd think it would be....

* Leaving the Post Office today, Nixon points out an elderly gent using a cane.
Nixon: What's wrong with him?
me: *trying not to cringe as he'd said this loudly and there were 2 other patrons nearby* Nothing's wrong with him, baby. He's just old....umm, he's lived a long life.
Nixon: Why's he walking funny?
me: Well, part of living a long life means your body doesn't stay fresh. He's using a cane because his body needs help.
Nixon: Oh.
me: But he's also really lucky. He's lived to see a lot of birthdays! And that's pretty cool, right?
Nixon: He's had a lot of cakes?! That's awesome!

He has a twin bed, but seems to only need the top portion where his pillows are...
