There was a period in my life where I chose not to speak due to my stutter and I used post its to communicate. I went to the bank one day to cash a check and I wrote on a post it that I lost my voice and I wanted to cash a check. Well, when I handed the post it note to the bank teller she pushed the silent alarm button and there were 2 security guards behind me and the local police were enroute. I was whisked away to the bank manager's office and I explained why I did that. (Mind you, the bank teller never opened the note, she just assumed I was there to rob the bank😅😅😅
