It was a hectic day today and we spent more time than I planned in Ikea. By the time we got home I had exactly one hour (assuming I wanted to be ready for my 6:15 client by 6:00pm) to run to the copy store to copy my quarterly taxes so I could drop them in the mail (tomorrow is the deadline), rush home, make dinner, eat dinner, be dressed and ready for class. Needless to say, I needed that entire hour! A 25 minute early student definitely wasn't going to work with my crazy schedule.
When she rang the bell, I got on the intercom and lied. I said, "I'm with a student, we'll be done at 6:00pm." That sounds much better than "I really have a wall to wall packed day and desperately need you to NOT be more then 15 minutes early or I just won't be able to fit this in." But I think from now on I'll just let students know I arrive at the studio ten minutes prior to their lesson and then 10 minutes prior to the lesson I'll walk into the studio and wait for them.
