Another great story. The immediate mental changes forcing them to act according to their current roles and ending the story with what happens to Beth & Emma post swap was well written. Also kudos on weaving in Murphy's diner and Carly into the story.
Nicely done story! I like the idea of the swap between the student and the teacher. Hopefully your next story will have the element of permanent mind change with both characters force to accept the new identity. Keep up the good work and looking forward to your next F2f swap story!
