Note on Abandoned Luggage is a written note found in Dishonored 2.
I've packed everything like you requested and brought your luggage to the train station, but I can't wait any longer. The train will be there any minute, and I won't miss my chance to leave this wretched city. Your shift at the Royal Conservatory should have ended an hour ago, so I'm confident you'll be here soon, and that you'll buy another ticket.
It has been an honor to serve you during these two years, and I wish I could have said goodbye in person.
Best of luck
The note can be found at Addermire station platform during the mission Edge of the World.
