Can they love ?

Tweet

I've watched a report of a boy and a girl who are both mentally handicpped.They are in a special institute where they are educated with a group of young people who are the same, with the adults figures but the children's intelligence.The boy loved the girl at the first sight and now they are a couple.The boy said to the reporter that his dream is to marry the girl and live together with her for lifetime,and earn money to support the family. How simple they are,and how cute they are.They believe love is love,having nothing to do with others.But I can't help wondering can they have a relationship as the ordinary we are?If so ,what about their future,I mean if they have a baby?
