What might you suppose he is doing?

sobering up enough to safely drive

J/O

waiting

Texting, or updating his Twitter, etc, etc,.

He's going to kill me. Eventually.

Do I get the porn mag?
Why not!?
No, hang on...there's a woman at the cashier
So?
Well she might laugh?
Are you kidding me?
No, she may think I am a pervert
Well you are
Yes, but I don't need people to know that I am
Well go to the shop on Acorn Street
But that might not have the mag I want
Well get another one
Like what
Well what do you like?
Well I like lots of wom...hang on, why should I tell you?
Because I am you, idiot.
Oh yeh

I don't think I'd waste my time entertaining the idea.

waiting for someone, watching someone, car broken down and waiting for help, having lunch & listening to music, taking a private phone call .................loads of reasons.....(if it were me, I would do this waiting for my wife to stop shopping especially in this heat where I would have the AC on

It depends on where he has parked and the appearance of the man and the car. I certainly do make snap judgements about people, but generally based on rather more information than this!

I'd probably figure he was just killing some time before he had to be somewhere else, or was taking a nap, or something harmless. It would depend on where he was, though. If he were in a parking lot, I would figure he was napping/resting/killing time. If he were in a residential neighborhood with nothing else nearby, I might be a little suspicious if he stayed for more than a couple of hours, but not for one hour. If he were at a drive-in, I'd imagine he was watching a movie!

I would think it was CK

He's a dealer. Or a hit man. Or he just wants some time on his own - he's thinking.

Although my perception would different whether it was day or night, whether he was in a car parked on a street or parking lot, etc. Is he fiddling with his phone?

On his lunch break listening to the radio and eating his lunch?

It's just me waiting for my wife at a hair or doctor appointment. She doesn't drive.

We had a guy one night parked in front of the house for a long time with the motor running, He didn't appear to me moving. We called the police and it turned out the guy was drunk and was able to park before passing out.

waiting for his wife to finish shopping

Reading, sleeping, on a stake out, stalking...

if he's sitting by school. I'd call security.

Hes casing the bank across the street to rob it.
He a pervert watching children in a nearby park or school yard.
Hes been stoood up by his wife/girlfriend/boyfriend.
Hes a cop working a stake out.

spying, waiting for his woman or mother to come out, avoiding facing what he is there for, waiting for his target to show, doing what I do for a living...

Unless it's a teen with nothing better to do, or someone who's home is stressful, or it's outside a store, I generally figure drugs are involved. That's my only experience. People don't have their life together if they have to wait an hour for someone else to leave the house.

Except that sounds to me like one of the most legitimate reasons to be waiting in a car, to pick up your child. If you were arriving from some other driving location with time to kill, better to wait at the destination. Besides, schools are usually more scenic than places like supermarkets.

He's waiting for his wife. She's getting her hair done.

It must not have turned out that well. She's coming out of the liquor store now with a stocking over her head.

< snicker >

Waiting for someone...

He is homeless, he lives in his car
