I haven't told anyone this, but at one time I didn't know how to eat full size oranges.
How did you learn how to do it?
I didn't know that you have to cut it into pieces. Until I saw you do it I never knew
It's good that you eventually learned. Learning how to do basic tasks are important our survival.
I never knew and I didn't even know other people had this knowledge as well.
Yes, it's pretty basic knowledge. You can improvise a little bit, but basically you don't want to get juice all over the place.
