Suicide, and Other Acts of Selfishness

Edge-of-nowhere, Glasgow, Central Belt. An abandoned, derelict bridge. A young man and an old man decide to take their own lives. In the same spot. At the same time. They've never met and they didn't know the other was going to be there.
They both know what they're there to do. It's just not so easy with someone else watching. No problem. They just have to convince the other to let them go instead. Easy.
