Banana is my favorite fruit. I don't think I would be able to see a nicely ripe banana on a shop shelve and I won't buy some from myself. My love for bananas dates back to since when I was a child.
Banaba is so expensive even being favorite fruit for some people. You can't afford the cost despite you like it @Fidelia. This is my point of view only.
I like mangoes. They are sweet, little bit sour. I like the tangy taste of mangoes. Mangoes are also native fruits, meaning they don't have to be exported, so they are cheaper and during mango season I sometimes eat one kilogram of mango at one time.
