In a 2021 survey commissioned by the website cars.com, 54 percent of respondents said they drive their kids to school, with 38 percent traveling by bus, 12 percent walking and 9 percent carpooling.

While the data indicates nearly 1 in 110 high school kids travel by carpool, sharing the responsibility of taking your kids to school with another parent is not without its problems, like the one faced by a parent who took to Reddit with a carpool-based dilemma.

Writing under the handle FiveStarFrontDesk in a post upvoted over 5,000 times, the mom explained that they recently organized a “small carpool” involving a set of twins who live nearby and another child from a different grade at their kids’ school.

Ahead of a recent pickup, the mom got their 16-year-old to message the two sets of kids to remind them what time to be there.

But while the twins were “waiting outside” and ready to go, the other child was nowhere to be seen. The mom even had her older child knock on their front door “twice” yet there was “no answer.”

Left with little option, they simply “took the other kids to school” and carried on with their day. The problems began when they got to work and saw they had “3 missed calls and a couple of angry voicemails from the kid’s mom” who was furious at them for not picking up their child.

“I called her back and told her how my daughter texted to say about what time we would be there,” the mom explained. “That my daughter knocked on the door when her kid wasn’t outside waiting, and they didn’t answer.”

Despite this explanation, the kid’s mom insisted that they should have called her son to “wake him” and could have “waited until he was ready.”

The Reddit user responded that “waking her kid up is not my responsibility” and they didn’t want the “other kids to be late to school.”

The other mom proceed to call her a b**ch before hanging up.

Furious at this response, she said she contacted the other parent to explain the situation and let her know they would “be dropping out of the carpool.”

However, this other mom said she too had encountered “trouble” with this other boy and suggested they should set up a new carpool system without the other child.

Left feeling guilty at getting the first mom and her son thrown of the carpool agreement, the concerned parent took to social media to see if she had been wrong to react the way she did.

Most fellow Redditors felt her response was indeed the right one.

“It’s insane to expect anyone else to be responsible for you getting your kid up and ready for school,” IChooseSnorLax said. “I wouldn’t even feel badly about it. That level of entitlement is astonishing.”

Hoistedonyrownpetard added: “Most parents would have had their kid call or text to apologize for making you wait.”

K1p1koder commented: “Maybe if they apologize and promise to get their kid up and out the door you and other parents might reconsider. Maybe not. Either way, not your fault.”

StrangerOnReddit, meanwhile, wrote: “That mom doesn’t understand that carpooling doesn’t mean pawning the responsibility of her child off to another person. He’s old enough to be able to be ready and waiting at a designated time. If he can’t do that then he shouldn’t be carpooling.”
