Love Sick

So third grader, KA, says to me "How do you know if you love somebody?"
Me: "You mean someone like your mom?"
KA: "No, I mean a girl."
Me: (Thinking "what do you think I'm not a girl? thanks bud!" Which is quickly replaced by "holy crap, you are only 8...I don't want to listen to this...but on the positive side it does answer that question of whether or not he is gay)" Well," I begin, " when you are in love your body feels all tingly when you get near that person and you really just want to be around them all the time because they makes your heart feel good."
KA: (who now drops to the floor and with a big sigh declares) "I guess I'm in love then."
