A couple of people sit outdoors at a table with an umbrella and talk.
A couple people sit outside in the rain at a table and argue about who's fault it is for being outdoors in such weather.
They can have an umbrella outdoors without rain. Not knowing what they are saying leaves us ignorant as to whether they argue about who's fault it is for being outdoors. People sit outdoors in such weather as they please, good or bad.
