This is a natural thing to do, but can harm some applicants. I did my adjustment with a lawyer, and recommendation was to give short answers, stories was a big no-no.
So the question how we met was answered in a short sentence: "we met at a conference".
And this was enough and satisfactory.
The problem with stories:
1) Officer doesn't have time to listen
2) When they do, they may use details against you! Or ask to elaborate on each point
So unless they ask for long answer, general advice is to keep things short!
