The real world ramifications of the film 'Big'!

Everyones seen 'Big', right? Y'know, kid makes a wish to a scary carny machine, wakes up the next morning and is Tom Hanks! Moves to the big city, in this case New York, gets a job at a toy company, meets a hot girl/woman, yadda yadda yadda goes home, becomes kid again. You know the film i mean, right?? Anywho, it got me thinking (as do most films that end in this fashion), what actually happens when he gets home? I mean, i know that the movie is set in the fictional world but wouldn't there be an AWFUL lot of questions about this scenario? Think about it, the mother thinks her child has been kidnapped by the strange man who was suddenly in her house one day, who was actually, her son, all growed up! He writes a letter home home to his mom, saying he's being treated fine and it's alot like summer camp! Surely the police would want to know where the hell he was for however long it was(2 months ish?)! Now i know that once he's given the description of his 'kidnapper' to the police, they would be off on some wild goose chase but surely they have to take into account that the kid may have been abused? And obviously, if they asked him he's gonna say 'No, i was treated fine and given lots of toys to play with!' which, from they're perspective, smacks of denial! So would they then 'examine' him for sexual abuse? I mean technically, he's being accused of sexual abusing himself as a child, only to be violated by the police to see if he has been abused!! Talk about irony!! And if he does 'fess up' and say 'Ok, i made a wish on a scary carney machine, which turned me into a grown up...by magic!' then i would think it's off to the psyche ward for him! It reminds of Terminator 2 where they do actually ask these questions of the main character from the previous film(Sarah Connor) and she does end up in the looney bin going on about killer robots from the future! I'm thinking this kids life after his incident won't ever be the same again and when he does grown up to look like Tom Hanks will he be arrested for fitting the profile of a kidnapper and possible sex offender from 20 odd years prevoius? How good a sequel would that make! ho-hum!
