going out

リーダーズダイジェスト４月号の"Life it's really like that"コーナーからの記事です。
I was driving around and around a parking garage in search of an available space. Nothing. Then I noticed a couple walking ahead of me.
"Going out?" I called to them.
"Just friends."
デートすることを "go out" とも言うことを聞いた事がありますが、当然デート以外の意味でも使うので上の記事のような紛らわしいことになるのですね。　ちなみにOneLook Quick Definitionsで "go out" を見ると次に示す六つの意味が載っていました。
・go out of fashion; become unfashionable
・become extinguished
・leave the house to go somewhere
・take the field
・date regularly; have a steady relationship with
・move out of or depart from
Well, I have to go out to the office now.
