Opening the envelope

This envelope appeared on my desk Tuesday while I was away from home. Maybe I shouldn’t leave the door unlocked.

I open an imaginary envelope every morning looking inside for the day. (Something I learned from dear friend Berta.) Are there things I Have to do, Need to do, or Want to do? Sometimes it’s empty, and sometimes it’s not.

I found this in the mysterious envelope.

Oh boy! A party. Can’t wait to find out more. Have to think of a costume.
