Abra and Open
Abra sat near the front of the classroom, purposely trying to distract others from noticing her uncle as they walked into the classroom. Little Eli had caught on way too quickly.
Abra would send someone a sense that they wanted to say hello to Abra as they came in, or when they sat down and took out any pens/pencils, she'd make them roll around the desk. If they opened a notebook, she'd make it close again. All harmless, small magic tricks. Anyone she knew personally might also get a zip-zip (hi).
