The "ok" sign thing pissed me off. I had learned from a very young age that it was sign language for "ok" (it combines the signs for the letters) and when I went to swim class, my mom would watch and when I'd look over to her she would sign that to me that everything was ok, and sign "I love you" (🤟 — not to be confused with 🤘ROCKANDROLL🤘) to me as well. For the record, no one in our family is deaf, we just learned some basic sign language because communication is cool.
