Scene: Waiting for the 24 or 35 at Castro & Market. Overcast, but mildly muggy.
Skinny son, switching his hips to a silent samba: You know Mom, you worry too much.
Chubby Mom, resting arms on cross-slung over-sized purse and food baby belly: I know, I worry about everything. I'm working on it.
Son: No, I mean you worry about me too much. You should worry about yourself more.
CM: What do you mean?
Son, head slightly cocked, weight shifted onto one leg, hands dug into the padded straps of his backpack: You know, Drink less coffee, Take your vitamins ...
CM: I know, you are right, I should exercise more.
Son: Yes putting hands in front of belly and small of back like a mom sandwich: Then you can shrink this!
