A friend in need is a friend indeed

Once Tom asks Leo, "Yo, Leo! I'm moving this weekend, wanna help me load some heavy furniture into the truck?".
"Nah", answers Leo, "I really need to wax my Porsche! The poor thing hasn't been waxed for weeks, man!"
"Not even if I say we're gonna have BBQ after unloading the stuff at my new house?"
"Do you hear car alarm, Tom? I think it's my Porsche! Gotta run! See ya!"
And so it has always been -- Leo is waxing his Porsche, Tom is hauling heavy stuff, having BBQ afterwards. Until one day a series of very unfortunate events happened: stock market collapsed, Leo's job got outsorced to Bangalore and his three daughters got married within a week of each other. Now poor Leo drives a beaten old rusty Datsun and never misses a friend's moving day, where he has the most couches to pull, and then the first at grill to drool.
Or how Tom likes to put it, "a friend in need is a friend indeed".
