Dragon said it first way back when. Actually what he said was a very calm, "We're in love, you know."
i think i responded with, "What's this 'we' business? Do you have a tapeworm?" (i had not learned to curb my smart-ass side back then)
In our case, i was the one who fought it like a tiger. i could have long, boring debates on the intellectual validity of the concept of love. (Yes, i was a severe intellectual geek in my younger days.)
