returning to comment
You can press the 'back' arrow on the top left corner of your screen.
It takes you back to the page you were on previously.
The more you press it, the further back you go.
And BTW, I love so many of the comments that people leave.
I always read them and really enjoy the witty remarks.
They make me smile.
And I have to laugh when I see a comment that I left and I have no recollection of having said it, but it was just what I was about to type in.
