Stolen from Nick's blog:

Kat: hey, my life's pretty boring right now...I need to keep tabs on other people...hehe
Nick: and i need someone to talk to, so its a symbiotic relationship
Kat: wow. so, if we're a lichen...am I the fungus or the bacteria?
Nick: lets think of a better example
Kat: no wait...it's algae....
Nick: im the humming bird and your a flower
Kat: right. good idea. No more lichen.
Nick: haha

Aaaawwww I miss Nick. And he can call me Flower, if he wants to. (Think skunk from Bambi.)
