At 13 I wrote, "Enjoy life. There's plenty of time to be dead." Barely a teen and quoting Hans Christian Andersen; I thought I was really "deep" back then. But I was furious when someone spray-painted something stupid over it. ;)
"You are light"
In Ireland, at the Cliffs of Moher. In the public restroom there were lots of posters about help lines to call if people felt suicidal. Apparently the cliffs (so breathtakingly beautiful) are a magnet for jumpers)... There were also lots of scribbles by people who wrote religious epitaphs (probably intended to be helpful but were rather condemning)... and I just felt compelled to write, "you are light"...
Does my ex wifes phone number on a bathroom wall count?
Yes, for a good time call this number....it was my ex best friends no. I know...I was 13 at the time.
