My grandpa smoked since he was thirteen
Does anybody know?
I am not sure. I would assume so since he has done it for so long.
If he's sensitive about his smoking, you shouldn't be broadcasting it on Facebook. How would you feel about your grandfather revealing embarrassing, personal details about your life?
It's my grandpa, he can do anything he wants.
But if he did everything he wanted you would eventually be upset. He would say something that would hurt you and you would be angry at him.
