The Handwriting

The note by the cups is in blue ink. Cream stock. The M is the one you make when you are in a hurry and want to be seen not hurrying.

It is your M.

It reads: If you are standing in the kitchen with both cups, you have been here before. The coffee is the same coffee. I made it a long time ago for you to drink later. That's what a lighthouse is. Light you spent in advance.

You sit down in the chair with the shape of you in it. The cup is still warm.

If you wrote down THAW, the ink under your thumb is the same blue as this ink.
