Love to me is someone or something where there is dedication, respect, and caring. It is not sex or even acceptance. It goes deeper than this. Think about when you see a loving family, and they are there for eachother, concerned for eachother, that is love. Not something that is superficial or with standards. Its true devotion and caring, love through thick and thin.
For some people love from their family/parents is all they have and ever had. And some people dont even have this. Some people ignore the fact they have people who love them.
