I'd like to call limes lemons
Why do you call limes by the wrong name?
I do it just to be interesting.
I understand you might be bored and what to do something funny, but you might confuse or annoy someone who was actually looking for one fruit or the other. Sometimes it's best to know when to joke and when to be serious.
I guess it could become a problem but I had never really thought about it.
I think it is best that you understand the problem. It is important to be accurate about food.
