That little red headed girl was me and while I still have the red hair and more freckles to count I am more confident because I had a big sister to show me love and compassion and be there for me in a time that I thought no one had the time for me.
I cannot tell you how much having a big sister affected my life. If you have spare time I would encourage you to look into getting a little brother or sister. It does not take very much time every week and can be done without spending a ton of money. There are lots of options to do without spending money. You could teach them to cook, work on homework with them or just taking a walk to discuss their day.
