It happened a long time ago. ✬

You should have told me a long time ago. ✬

I was here about a year ago. ✬

I met her an hour ago. ✬

It stopped snowing an hour ago. ✬

I remember it as if it were yesterday, but in reality it was fifteen years ago. ✬

How long ago did the bus leave? ✬

What has become of the book I put here a few minutes ago? ✬

It was ages ago. ✬

That was only a year ago. ✬
