It took Allan Gieger Jr. 10 minutes to write his Craigslist post and then share it on Facebook. He was angry, but he was also hesitant.

Should he have shamed his only child like that? Then again, his 18-year-old, a young man who shares his father's name, knew better than to embarrass him by walking off a job with no notice.

"I have my son's truck up for sale that I bought for him as his first car," he wrote. "He thinks it's cool to drive around with his friends smokin dope and acting all thug and especially not showing me and my wife the respect that we deserve," the post read, offering a discount to anyone who lived on the Westside so that his son could see the car on the streets.

Immediately, he felt regret, and he thought about deleting the post. No, his wife told him, we have to do this.

His friends shared the post, and their friends shared the post, and within days, as one of his friends wrote, "You've gone viral, my man." On Friday, a Westsider put down a deposit.

When young Allan Gieger III first saw the post, he was angry. He knew he'd done wrong, and he knew he shouldn't be smoking pot, but he felt as though his dad had gone out of his way to make fun of him. But more and more people shared his dad's post and declared him father of the year. You're lucky to have such a dad, someone said, and that made young Allan think. Later he would explain, "I'm just kind of a hard head and it never really clicked in until now."

He and his dad had always had a good relationship, and he knew his dad saw himself in his son. But he had been a disappointment lately. Though he never got into trouble with the law and he planned to graduate from an alternative high school, his dad could smell the pot in the truck. When friends came over, his dad would demand respect.

The final straw, Allan Geiger Jr. said, was earlier this week. His son had missed two days of work because of a rash, and then his wife dropped Allan III off. Not long after, Allan III came home and said he'd been fired for no reason.

Then the boss called the dad and said he hadn't been fired, he had walked off.

His son's discipline had been an issue for a year. Allan Jr. worried that marijuana would lead to harder drugs, to prison, to death. He had tried taking away his son's cellphone, taking away social media, talking to him.

Now, he decided, he would put it online where his son's friends could see. His son would get a taste of the embarrassment he found out his son had lied.

After the post went viral, father and son talked. Allan Jr. said he was disappointed. Allan III said he understood.

"The way I feel toward my dad," Allan III said, "me and him, we've always had a good relationship, a good connection."

"I love him to death," Allan Jr. said.

But that doesn't change the fact the car is still being sold.
