Sugar Cookies and Baby Powder.... That's What Grandmas are Made of!

My grandmas made me grilled cheese sandwiches and let me decorate cookies. I grew up with my grandma taking care of me after school. I learned to be mellow, talk softly, and to enjoy watching birds and squirrels in the back yard.
Based on my experience with my grandma, I can see why I am having such a hard time with my son's friends grandma.
My son's friend goes to his grandma's everyday after school and my son had a playdate at her house today.
I may not let my son go back. This grandma gave the boys toast and coke for lunch. It was followed by two pieces of bubble gum and a sucker. Are you kidding me?
The worst part is when I picked my son up he smelled like he had smoked a pack of cigarettes. He hadn't of course, but the grandma smokes in the house.
I admit I knew the grandma smoked, but I guess I thought she wouldn't smoke around kids.
My son on the way home told me he thought grandmas weren't allowed to smoke. I told him sometimes they do, but it was a bad habit.
He then told me he and his friend visited another friend that lived two blocks away. He said the grandma didn't go with them, he and his friend went alone. They are both only in kindergarten. Not okay!!!!
I'm annoyed that this grandma isn't like my grandmas or my son's grandmas. They aren't supposed to smoke and they are supposed to make you eat healthy and play safely..... What the hell?
