I'm taking ASL classes for many reasons:
1. I've been HOH since early childhood, but raised orally. Listening and sometimes speaking is quite an effort, so I avoid situations with friends and family that aren't 1 on 1. I thought making Deaf friends and using ASL might be a nice change. I must say that, despite my not being quite fluent, I can sit in a room full of people I"m communicating with for hours - voice off & HA off - and not be exhausted or frustrated or lost: Exactly what I was looking for.
2. Sometimes friends, co-workers, people I volunteer with, some waiter at a restaurant (no joke), etc come get me to help in a situation if there is a Deaf person having trouble communicating (I probably sign, right? I mean, I wear hearing aids :-P). Usually, all the person wants is a piece of paper to write on (obvious?), but still, only having the ability to fingerspell, I have felt stupid in that sort of situation the few times it has happened. Knowing ASL would be nice for next time.
3. Having poked around (mostly due to my Oral-HOH/what-else-is-out-there curiosity), I've seen that ASL is a beautiful language and Deaf Culture goes right along with it. It's interesting and I'd like to learn more for that reason, too!
4. I intend on having children in the next few years, and children who are raised multi-lingually store language in a different way than people who learn only one in their early years, so I would like to have all of my kids learn ASL from birth. For that, I need to learn it first
5. Children can sign before they can speak, so it will afford our family more effective communication early on.
6. My husband and I are looking into adopting, and since we will have a bilingual household, anyway, there is definitely the possibility of adopting a Deaf child.
Hmm... I think there are more good reasons that I've thought of, but those are the ones that popped into mind right now.
