Hello Damian! Welcome to our deaf community! Thank you for being honest and open that you are willing to learn ASL and deaf culture. I am myself deaf since birth but I do have both hearing and deaf friends. Each deaf individual is unique and have their own preference of communication. Some prefer to sign ASL only, others prefer total communication (using both ASL and oralism) and it’s all up to them. It’s awesome for hearing people who are motivated and wanted to learn ASL. Hearing people can be great servants such as signing for their deaf customers at Starbuck. I do sign with Starbuck employee if I want to order my favorite drink. I think that’s wonderful.
The key is patience and be extra aware of deaf people’s body language and facial expression. We the deaf people depend on visual as we use our eye for most of the time. Lysander is right about taking ASL class. It’s the best way to start there. Once you are getting better with signs then you can proceed to advanced ASL class.
I have a friend who is deaf and is a ASL teacher. She’s a wonderful lady and happened to be a Christian. She would sometimes invite me to her ASL class to help her students to get know about me. Some of them have never met a deaf person or know nothing about deaf culture. It’s a great way to meet new people and practice signing with the deaf people whether it’s at a deaf event, church (we have a deaf congregation and it’s also a great way to socialize with them), deaf club and many other places.
You are in my prayer.
God’s blessings
