They have been together for 50 years now and one day Gilbert return home to a empty house and a note saying “find me” with a red tread attached to it. It leads to the kitchen, then the living room, then their room, the study, then outside, pass the garden and into the quiet woods behind their house. night is falling and fireflies are flickering and he still follow the tread.
He find Matthew waiting for him making figures with the red tread in his hand and smiling brightly.
This is a bit sappy but the fate and soul mates prompts is the best for that.XD
