what a lovely story! This reminds me very much of my best friend! We have been friends since about 8 years old.. off and on when we were younger but always in the same crowd - it wasn't until we both ended up pregnant around the same time that we really joined forces LOL shortly after that her mother died and I did the same as you - took care of all the little things for her. :-) We've had plenty of fights.. once we didn't talk for almost 2 years LOL but you know what? We finally broke the stubborn silence and were back at it like nothing had happened lol
I've added your entry to my list and thank you again so much for sharing this heart warming story of best friend love! <3 <3
