Everyone needs to learn sign language pls. Like whatever version is used in your country I encourage you to learn.
Not only will you be learning another language, but you'll be able to talk to other signers, D(d)eaf or not, and two people can communicate in loud places without needing to hear the other.
I'm hard of hearing and have such a difficult time with trying to hear others. I stopped wearing hearing aids because I got annoyed that even after about 18 years I still had a hard time distinguishing what hearies were saying.
I'm learning my country's sign language (ASL) but don't have any experienced signers to practice with. I really hope more people learn these languages (and the history of said languages).
And sign is also helpful with neurodivergent people and babies aswell!
