Your "boring" example might be more effective this way:
I rinsed the dishes before putting them in the dishwasher. Since they were needed immediately, I dried them by hand with a towel.
"We" was changed to "I" because dishwashing because too many dishwashers are hell on the dishes.
Your instinct to avoid repeating "we" is sound.
