Tell a funny joke?

True story, I run a dessert shop, and an old lady often comes to buy things. Once grandma came to buy red bean pie again. As soon as I saw her, I said happily, Grandma, I have missed you for a long time. I just talked to Aunt Zhao about you and said that you haven't visited our store for a long time. Grandma said, I miss you too. I didn't go out because it was a little far from here, my legs and feet were inconvenient, and it rained all the time. Every time the old woman comes to buy red bean cakes, she always chooses, chooses and chooses. Again, this is too small; Then he said, this is too big for her pot; Anyway, there are too few peas in it. She does this almost every time, and it's hard to talk. But I always treat her patiently. This time is no exception, I said with a smile, grandma, you must remember to bring your pot when you come to buy it next time? Grandma said, what do you mean? I explained that if you bring a pot at home, you don't have to worry about buying a red bean pie that suits your pot.
