#14: Home Alone
When you think about it, the idea of a whole family forgetting their own child/sibling is kind of ridiculous. Like how could that actually ever happen in real life? Well, the writers of the film include plenty of things that lead us and them to believe that all the kids are with them.

When cousin Heather does the headcount, you can see that she made a few mistakes, and counts people that shouldn’t have been counted in place of others. What can we say? Traveling with the whole family can be stressful.
