I think when it comes to falling in love.. parents won't be able to influence much.. so what is the point of parents trying too hard to influence - and worse, trying to stop?
The most important thing for parents is to try to support and give objective view.. Don't be too judgemental.. even if they fall or fail..let them be.. they will learn eventually..
