We mostly see "ago" comes with time periods like two weeks ago, two nights ago.
What about using ago with things other than time periods like page, post, bus, girlfriend, etc.?
Please check three pages ago to find the answers
Please go to three lines/paragraphs ago
Refer to two posts ago for more information (Instagram)
Did he leave with the last bus? - No, he left with two buses ago.
Sometimes, lines and posts aren't numbered so I can't say "go to line/post 14".
What is the right way to say these sentences?
