Dear {insert Friends name},
Im writing to you today to tell you about a discovery that i’ve made.
I was cleaning up and i stumbled upon a [message carved OR message written on the bottom drawer of one of the drawers] i found this quite concerning.
I mainly find this concerning because i have no memory of writing this, i planned on calling the authorities but i was unsure if your or another friend of mine wrote this as a prank.
Please get back to me,
Sincerely [Insert your name].
