Signatures

I think it's nicer to have my own, self-created signature; it adds a touch of uniqueness, so to speak.

You're right about that, but my signature isn't exactly unique.
In general, I like to quote philosophical statements from ancient Greek scholars and various writers in my signatures. Right now, my signature is a line from a song by the unforgettable band AGATA KRISTI, from my favorite song, SECRET.
