If you have a meal near the beach, you might see dolphins playing.  It is very relaxing when you watch them playing or just spend time at the beach.

Next notebook entry -- perhaps go into more detail about your city, and your job.  Normally, an introduction for a professional would have more detail.  As well, WHAT do you read?  HOW LONG have you been playing chess?  WHICH GENRE of movies are you into?  WHO do you go with?   I thought you lived in Tabasco....
