WAIT FOR IT

Being an introvert, I must say that one of my biggest pet peeves is having another person talk over the top of me in the midst of a conversation. 

First, do you understand how much effort I expended just to begin that sentence? 

Only to have you toss it aside to make room for your own?

I can understand a child doing this.

But a grown man?

(And, yes, I do find this more common among men than women. Do you?)

How do you function in life as an adult if you do not have the patience, grace, and manners required to allow another person to finish a sentence before you start into your own? 

It seems like a bare minimum for adulthood.
