Do you miss someone dearly who you have met in another country?

- i sometimes think about it and i have a heartache even though she is just a friend to me not a girlfriend. i met her in taiwan while going on a church's missions trip teaching God and english to kids as i met her. she is 22 i am 14 that may seem weird but age is not a problem to our friendship. just share your experience our any comforting words or advice?
