There is a lot of irresponsible parenting in this story. First, let's start with the stepsisters in question. This is a pair of 25 and 28-year-old single moms who were so reliant on the Redditor's 18-year-old daughter to babysit their kids that they couldn't possibly get a real babysitter to take care of them. So when it came time for a family vacation, the stepsisters tried to convince the Redditor's daughter to stay behind, despite the fact that she wanted to partake in some much-deserved time off as well.

Then, there's the Redditor's wife, who tried to defend her fully-grown daughters for trying to sabotage the 18-year-old's ability to join the family on the trip. These ladies stole her passport, leaving the 18-year-old and her father scrambling just hours before their flight departure. Tension was so high between all the members of the family that the Redditor decided to cancel the entire trip. Looks like his stepdaughters would have to take care of their own kids for a change.
