This flashback comes from April 2009 and is called:
My Busy Morning.
Flynn was waiting for a mousie so I decided to go for a walk on my own.
I stopped and looked at the daffodils growing in the field. When I see them, I know that Spring really is here.
All the walking made me tired so I stopped for a rest
Then I went and chewed on some grass.
After that I went to see if Flynn had caught the mousie but he had let it escape again.
I had a much busier morning than him.
