Why is it?

I've taken 3 spanish classes so that I can learn to talk to non-english speakers in my area, yet I can't bring myself to actually TRY to talk to them? I've got the perfect opportunity to practice. At my son's dojang, there are many bi-lingual spanish speakers there on a regular basis. All I'd have to do is ask them to help me practice. Yet for some reason, I can't bring myself to ask. I know I won't learn to speak well unless I practice and I've enjoyed learning. I guess I'm just afraid of making a fool of myself. I don't know. I've also bought a computer program to help me practice, though I haven't used that much lately either. Does it work as well to find someone to just send an email to? Hmm.
