It's the texture of the fruit as it is in my mouth and I am chewing them. There is also a taste factor with some of them as well.
I know that there are going to be suggestions forthcoming from members and I appreciate what you all are going to do, but I am 47 years old and haven't eaten fruit since I was about four years old. I am not going to start now. I am fully aware that fruit is good for you, but as I mentioned in another post, it is what it is.
I do eat some vegetables, like broccoli, cauliflower, carrots, onions and mushrooms. Oh and cucumbers in salad. I will eat spinach if it is cooked in something else, same with celery which has to be soft for me to eat it.
