I am mean

My son wants me to go to the store because he wants to buy a toy but he doesn’t have any money. I know I am mean but when he said he wanted to buy a toy I asked him if had any money: he said no and I said you want to buy toy and you do not have any money. Of course I will buy him the toy that he wants but I do not like to buy him toys because when I do after a few days of playing with it I will find it in the floor because he is tired of playing with the toy. Even when I was taking a nap he woke me up to ask to go to the store for the toys he wants. I never pay any attention to him and I went back to sleep but I told him maybe tomorrow we would go and he got mad at me.
