So basically how students write papers
You're viewing a single thread.
My friend says "long story short" then spends 25 minutes telling me about every detail of his doctor's appointment anyway.
I usually go with "long story shorter..." because I know no matter how much I try to condense things, my explanation will be long simply due to my need to over-explain.
I do this on purpose
I don't explain what the right answer is
I explain to context of what was considered before coming to the answer.
