* Having a sister is like having a best friend you can't get rid of. You know whatever you do, they'll still be there. * A sister is a little bit of childhood that can never be lost. *Big sisters are the crab grass in the lawn of life. *Sisters is probably the most competitive relationship within the family, but once the sisters are grown, it becomes the strongest relationship. * My sister taught me everything I really need to know, and she was only in sixth grade at the time. so to all who have sisters, you are very lucky..because a sister is always there whether in times of success or failure, they always on your side...:-)))!!!
