Home Alone fans convinced Kevin was purposely left behind after spotting tiny clue

mirror.co.uk:

For decades Home Alone fans have been willing to overlook the monumental parenting fail of Kate and Peter McCallister on one fateful Christmas.

Only mid-way through a flight travelling more than 4,000 miles away from their home do the pair realise that they've left their eight-year-old son at home for the holidays, giving him the responsibility of buying his own toothbrush and fighting off home intruders armed with a blowtorch and a gun.

But accidents happen. And it's an easy one to make - Kevin is told to sleep in the attic after causing a family riot over a cheese pizza, a neighbouring kid who has a similar taste in hats is mistakenly included in the head count the following morning, and it's all an innocent mistake.
