I am an ASL user.
Well, I can share my experiences with you. If the events for deaf people, then I tend to go and search for old friends, and grab my time to chat with them. I do chat with new Deaf people if they know who my old friends are. I admit that I do not have time to chat with any learning ASL people because the place is not for me to teach them at the Deaf events. I don't mind teaching anyone who wants to learn ASL, usually at my work or a small group at a friends house. It's the same thing for Hearing people who do with one Deaf person vice versa.
That makes perfect sense and it's completely fine
