What's in the bag? Small child or golf clubs

Walking out of the airport, I'm following a man with strange, long white hair - Dr. Emmett Brown style - and he's pulling a long, dark blue bag with white stripes down the sides. It's a little ratty and has a long, ragged hole on the right side in the middle. Sagging near the top where he's dragging it by the handle, the bag is obviously not full.

I can't pass him because we're both headed out to long-term parking and there's only one very small path to it. So as he is meandering under the weight of whatever's in the bag, I can't help but think what could be in it. He's carrying a backpack and wearing an old-school, green hooded windbreaker. That white hair flipping over the hood in the wind. A little creepy.

At first I think golf clubs. But no guy would treat his clubs that way. And this guy has probably never set foot on a golf course.
Then I think clothes but what a weird bag to put them in. He does have a backpack so probably not.
Small child? Would fit - the bag and the style he's sporting.
Then it hit me...if this is what I'm thinking, then what the hell am I doing walking so close to him?!

I look around. No one is anywhere near us. It's getting dark. We're in a near empty parking garage. So my brain goes to rape, dismemberment, robbery. And then I remember that I was taught Brazilian jujitsu and kickboxing. Sure, I could kick his ass. He's only 6'2, 200 pounds. No problem.
No cops anywhere. Don't see any security cameras. Even if I scream, the sound of aircraft taking flight would totally drown it out. Now what to do?

Then this poor guy takes a right, goes up the stairs and out toward his car. Wow - It's a good thing people aren't mind readers!
