Wow, he remembered that day. :-) You’re right, you were being nice by disciplining him. It was the most loving thing you could do.
Thanks. Icing on that cake. That same grandchild has 4 younger siblings. The last two are spoiled by tired parents. Oldest griping about them and said he sure wished I had been able to have them as much as I had him and the story would be very different. Indeed it would. Love kids, but demand good behavior.
