Be someone who does not demand the person you care for to be what you want, because you will not want to if asked to be someone else. We have to accept someone with what it is that someone also accept us as we are.
When a person who was with her boyfriend, she will feel very happy because God has sent someone good and accept what is to be his life partner.
When they lose the people we love will be very sad, a sense of loss will come at the end after everyone was gone from our lives. Be a strong person and do not let the sadness always comes. Make it a valuable life experience. Make your life a pleasure although sometimes depressing. Find friends that much, do not look for enemies and find the experience a lot, do not look for stupidity.
