Swimming before work

As I've spent my whole weekend on studying English, I felt very dull at the end of Sunday.
Therefore, I decided to go swimming right after I got up today.
Fortunately it takes only 5 minutes on foot from home to the nearest swimming pool.
Very easy.

Maybe because it was Monday morning, I felt lucky that I could have free room in the lane of the pool. After an hour, I came back home and ate cereal as breakfast, then left for the office.
Probably I would have good sleep tonight.
Actually I felt sleepy even when I was working. :-P
