also loopy signatures that have 1 big letter with a scribble behind it
Why you gotta call me out like that? Haha. But seriously, I had a proper signature until I got a part time office job at 17 that required me to sign a lot of things (for packages, receipts, witness acknowledgement, etc) every day - that's on top of initialing things. I worked there 5-6 days a week before doing that same job full time for a few years and
eventually continued part-time for a few more years when I was in another career. Anyway, the point was that it was a fairly busy job and the extra few seconds my full, proper signature I had developed wasn't an option and I slowly morphed my signature into a bastard hybrid between initials and signature that has remained some 20 years later. Also, I ditched the loopy first letter.
