I studied American Sign Language/Deaf Culture in college. I also spent as much time as I could immersed in a signing community, mostly Deaf. I also had Deaf friends. Between the exposure and classes I was somewhat fluent though I had much more trouble understanding than speaking. I think that because I have not signed for so long, I have lost much of my skills but also think they would come back if I signed everyday.
Congratulations on learning to sign. You must have good eyesight! I have a close relative who was born profoundly deaf due to her exposure in utero to Rubella before a vaccine was developed. (And this is why everyone should get childhood vaccinations!) I have learned from her that there is a big dispute and divide among American educators of the deaf about sign language versus lip reading and speaking. She started attending a special language school for deaf children at age 2 which prohibited the children from using sign and required them to learn to lip read and speak.
Today, she is about 53 years old and her ability to speak and lip read is phenomenal. She started learning sign language in her 20s and has many deaf friends who are limited solely to sign language so she often serves as a translator for them when dealing with the hearing community. She works for the local Sheriff's department and has helped them communicate with the deaf. She also has been married for decades to a hearing man and has two hearing children in their 20s who learned at a very young age that mommy's ears are broken and they helped their mother understand when people mumbled, or averted their faces when speaking, or had big bushy mustaches/beards that covered their mouths.
Her old school asks her to visit every year on parents' day so parents who just discovered that their children are deaf and are heartbroken can meet her and see that deaf people can have wonderful, fulfilling lives. She is also a role model to the young students as someone who has succeeded and is happy in life despite her deafness.
No one in our family ever learned to sign because she communicated so well by lip reading and speaking that it was never necessary to learn sign to talk to her. We chuckle at some of her expressions. My favorite is "turn on the lights, I can't hear you" because she "hears" by lip reading.
