person A: The other day I had a flat_comma_ but I had my floor jack and 4-way lug wrench in my trunk and was able to get my tire changed and get back on the road within 10 minutes.
person B: 10 minutes is a good time to be able to change a tire. I do not think I could change a tire own my own. 
person A: I've had so many flats in my life I've gotten quick at changing them.
person B: Practice makes perfect_comma_ or makes you fast in your case.
