Man, I just don't know how some people do it.
There's a retired couple in their late 60's or so that works out at my gym in the mornings. Always together. They go hop on the treadmills side-by-side and the wife literally just talks into her husband's ear, non-stop stream of consciousness without pause the entire time. He never says a word beyond "yep" or "uh huh" every now and then. Just stares blankly ahead. I presume at this point he just hears a high-pitched tone or something. After the treadmills, they go use various weight machines, and the wife always is on whatever machine is next to her husband, yakking in his general direction. I'd have to give up exercising entirely if every trip to the gym meant that my wife was gonna tag along and try to talk me to death the entire time.
This man appears to have the patience of a saint, but I just know that deep down, buried somewhere in his gut, there's a "goddamnit woman, do you ever shut the hell up??!???!" just waiting to escape.
