I meant innocence in terms of, them not a lot of baggage and instead being emotional stable and not too unpredictable or without merit. Throw a 16 year old and a 23 year old into a tough situation and the older one usually has more of a chance of making it through. I probably used the wrong word but I do find college kids can be sheltered, it depends on 'how' but there are some who haven't had to deal with certain conflicts or themes before, though it does depend a lot on each individual.

The UK or Korea would be cool for me. Honestly, it would be a coin flip. Did you have a city in mind for those? We could probably come up with 1-2 each and narrow it down that way?
