The questions on the Liebowitz scale mostly seem like they're directed at a different species from me, so I could get wildly different scores depending what values I plug in.
Am I anxious using a telephone in public? Not particularly, but I refuse to use them in private.
Do I avoid eating in public? Well it must've been quite some years since I last did, but I don't think that has anything to do with anxiety.
Drinking with others? Heh, it's not like I've ever had the opportunity, but I don't drink anyway.
Going to a party? My only party was 10 years ago, how should I know how I feel about them today or if I'd avoid when I haven't had an invite?
Working/writing while being observed? Well I suppose that'd be pretty creepy since I'd wonder how they broke into my apartment to watch and who they are.
Calling someone I don't know very well? Why the heck would I ever do that?
Giving a prepared talk? Uh, last time must've been 19 years ago.
Returning goods to a store for a refund? The last time that came up was 15 years ago I think, not worth bothering with cheap stuff.
Resisting a high pressure sales person? Probably not an issue but I bought my car on ebay in order to not find out.
Giving a party? Are you kidding me?
