when couples are shown on TV its always the same way, each couple are grouped together by their personality, because that's how society thinks relationships should go, they think that the only way to get along or have a healthy relationship is to have the same views, same personality, and same interests. in "parental Control" they parents want somebody they think is good for they child, they are asked to find 2 candidates that they feel have the same personality. and the child is asked to pick from their current BF/GF, or the picks of the parents, I'm not really sure how realistic the show is. so here is a question.

Are couples better off with the same personality, or different personalty?
