HOME Alone fans have been left stunned after spotting the reason why the family forgot Kevin.
The popular Christmas film became a huge fan favourite when it hit our screens back in 1990.
The movie follows a young boy called Kevin (Macaulay Culkin) who is left at his home in Chicago for the Christmas period after his family forget to take him to Paris.
Kevin gets up to all sorts while he's by himself, including protecting his pad from thieves.
However, one fan on TikTok has recently pointed something out about the blockbuster - that Kevin's dad Peter is the reason he didn't go on holiday with them.
Sharing a clip of Peter (John Heard) collecting rubbish and putting it into a bin, they pointed out in the caption: "Been watching Home Alone all these years and did not know that the dad threw away Kevin's ticket."
