Yesterday

I like this, but I desperately hope it never happens to me!!

Yesterday,
All those backups seemed a waste of play.
Now my chapters have all gone away.
Oh I believe in yesterday.

I…pushed…something wrong
What it was I could not say.
Now my thesis is gone
and I long for yesterday-ay-ay-ay.

Suddenly,
There’s not half the files there used to be,
And there’s a deadline hanging over me.
Office crashed so suddenly.

Yesterday,
The need for back-ups seemed so far away.
I knew my thesis was all here to stay,
Now I believe in yesterday.
