yes
Yes a ten year old can go on the Manta ride as long as they meet the height requirement which I believe is 54" or 137 cm or taller.
Taller than you
The average height of 18-20 year old females is 5'4''. Taller or shorter than that is also normal.Medically, an 18 year old woman should be anywhere from 4'8" to 6'8" tall. Shorter would indicate some sort of medical condition (possibly a hormone problem, or dwarfism), and taller would likely indicate a similar medical issue. Anything in between is normal.
Uhhh...could it possibly be Detective Conan?
Yes, but it is not appropriate. Answer The question is, why would an eighty six year old want to date a twenty year old - why could they possibly have in common with that kind of age difference?
He could be charged with corruption of a minor and harboring a runaway, and possibly statutory rape if they're in a relationship.
Report the incident to the police. Start by talking to a trusted adult.
