This is saddening news.. As a Father and Dad ( no matter how grouchy and pissy I can be ) it would tear my heart out to lose any of my kids.. Especially in your case..
I am a big ole, burly feller, and when I read your post it jerked tears from my eyes, in fact I had to leave the room after reading the original post.. My heart feels for your loss..
I could see the delight in his eyes, while he has hands mashed the icing on his cake.. I can say it was touching that you came here to share your sad news.. Our thoughts are with you..
Our dearest sympathies are yours.. Tim of T and J
