That was so very sweet of your son to do that for his mom, whom he loves so much. True love; real love is wanting the best for those we love more than we do for ourselves. Your son has already learned that and he is only 9 y/y. I am not sure what COE stands for but I assume that you have an illness or need of some type, maybe of the heart.
I was just praying the other night for a young man who needs a new heart; he has a wife and 2 children as well. Please do come back and tell us more about yourself and your family; we'd love to hear from you again.
