Dear Me...but what to write next?

I sat down now to write some "notes"'...
Some letters to some dear old friends.
They wrote and asked me how "life" goes; 
And told me how their path's now wend.

I contemplated what to write....
And wondered why 'tis lately so
That it's been such a chore to write
When formerly 'twas pleasurable.

Instead of grabbing reams with joy, 
And gladly stuffing envelopes, 
The lined pages sit nakedly, 
While I now struggle to write prose.....
