Is there an appropriate response to "Jesus Loves You"? For Catholics we've got a lot of cool call and response stuff built into our liturgies that can easily translate to everyday life.  So if someone in a truck shouts at me "Dominus Vobiscum", I know to say "Et cum spiritu tuo”.  

I was wandering around down in the southern US a few day ago and someone in a truck yelled at me "Jesus Loves You".  I thought that was wonderful and it really cheered me up.  I waved and said "thanks".  

Is there a cool thing that Protestants say (like "ping" - "pong" on IRC or that cool sign Harley guys do)?  I know Bill Cosby thought it was cool that Protestants say "Amen", but I don't think that's an "Amen" moment.  I want to say "Thanks for remembering me, Jesus loves you too!",  I don't want to say "I know, ain't I cool".  

Also, and this may be pertinent information to the question at hand,  I really did look like a hobo at the time.  I was walking from a Motel 6 to a Wafflehouse wearing 3 shirts, a jacket, a scraggly beard a stocking cap and carrying a mug and I'd just been camping for the weekend, the fact that I left my sleeping bag and over-stuffed backpack in the hotel room didn't seem to improve my appearance.
I guess if I was in Italy and someone said "Jesus loves you" in Latin, I might reply "et tu frater" or "et tu sorror".  Don't know if I could get away with "Jesus te amo" or if that would give out the wrong signal, though.

In English, I would probably respond with "You too, brother" or "You too, sister".  Or perhaps "Such love! Amazing love!" accompanied by a great big smile and a cheery wave.
