do you think we can deliberately chose to fall in love with someone?

I'm not entirely sure what you're asking, really. In cases of arranged marriages for instance, I've read that sometimes the couples do end up falling in love with one another even though they didn't start out that way. But I don't know if you can set your sights on someone and force it to happen. Too many variables, not in the least the opinion of the other person, you know?

Have at it.
