Don't you hate when you have to give stuff away and then can't? Well, that happened to me recently. I was going to give away some of my son's old toys, but started looking at then and realized that I need to keep them for no other reason than that I was being sentimental 
I know! I am always like I need this notebook that has my 3rd grade handwriting back from the 90s because it will be very useful someday... lol
