Should I lie about being sick at work to go to a baseball game?  My brother is in town and he got us tickets.

In general, it is not advised to lie to your employer in order to take a personal day off. However, in this specific case, if you explain the situation to your employer and emphasize that you will make up any work that you miss, lying may be the best option since it would allow you to go to the baseball game and spend time with your brother. If you do decide to lie, it is important to choose your words carefully and be prepared to back up your statements with proof, such as a doctor's note.
