David Sanders was my school principal.

I once ███████████████████████████.

I think to like, show the security guard outside, so I could leave school early.

(I think "once" might be a little bit overly understated.. )

But really, Principal Sanders, thank you for taking an interest in me, the well-known CIS student.

A tragic, transformational figure...

I write my signature as L E.

You used that simple mark because, as the CIS principal, you had many certificates and documents to sign.
