Notes

This morning, in the car on the way to Pathmark, I thought of the beginnings of a poem/riddle. Each line would contain a key word, and the riddle answer/common element would be what all of the key words have in common. I'm noting the words here, since it's unlikely anyone from the Riddle Room will see this:

Sky: sun, moon, star
Traffic: red, yellow, green
Emergency: lamp, flash, head

Figured out the connection?

I wish I could start working on it now, but I've got to go to a clarinet lesson in like 10 minutes. Oh well. And it's really hot today too, I'm pouring sweat. The loft traps too much heat. *mutter*
