Thank you. Sincerely.
That was a 1 not a 4? And yeah, the most confusing part is the line is solely under the 2 and the 6, as if saying to swap those numbers. Even then, it would look like 327 and leave another digit out, so I assumed 42 was replacing the 6 like 3427 though I tried a lot of combinations using the 12 as well. Would have sworn the 7 was at the end considering the line connects the 12 to the 6 as if to say it the twelve belongs in the middle rather than the six. I'd suggest a bar connected to the line that goes under the 67 and the 12. Also, why is that a 1 but look so much different than the 1 in the 17 in the upper middle? It even has a bend like a 7 or 4 @.@
But that leads me to the real question of if someone makes a pin for their own phone... even giving the benefit of the doubt their memory could be atrocious... why are they writing it down in such a convoluted way if the note is for themself? lol
