Rejecting someone's love or (even worse) laughing at it, would be the crime against the friendship - the wound made in the other person's soul. But when the love comes - what to do with it? We have to be responsible - act as the rules of our society tell us. And first of all - don't do harm to people around us. Sometimes it means we have to establish the limits and do it with all possible delicacy. Behaving like those people jumping on their heads into a shallow water is never good idea.
