Present simple: third person singular

We need present simple to talk about our best friend's free time activities.
Look at the example:

This is my friend Angelica. She plays a musical instrument once a week. She goes dancing every two weeks. She paints or draws twice a week. She goes to the cinema every two weeks. She watches TV once a week. She reads every day. She plays video games twice a week.

To form the present simple, we normally add an -s to the verb in the third person (he/she/it). 

Example:
1. Maria likes playing sports.
2. Camilo loves painting.

There are exceptions add -es to the verbs do, go and watch (she/he/it)
Example:
1. Teresa watches lots of TV.
2. Anny does chores
3. Camilo goes to the beach
