Well Ladies, Its a good thought but some how does not make much of a point. For one thing, none of the other people in the family than our life partner can we have emotional as well as physical relationship with. So your point of adjusting with everyone is good except for life partner as we have to not adjust but connect emotionally as well physically with our life partner. Otherwise, we will become almost incapable of adjusting with other people as our basic need of satisfaction (both emotional and mental) isn to met. The next thing is that, brother/sister/mother/father/son/daughter all come to only a certain stage along with you in life but only your life partner is there for you always whether he/she wants it or not. So its very important for that person who is with us to be able to decide whether it will make them happy to suffer for you or not. Again, whats the point if one is not staying happy with us or if we are not staying happy with our partner at all times. Thats why god gave you choice of choosing a partner who you can live with and decided your mother/father et all his own;knowing that we can adjust. Couple of meetings will reveal nothing but how the other person wants to project himself to you. If you believe a person based on couple of meeting and decide on his character and hope it will lost for life time, then GOD be with you at all times and save you both.
