Re: New to it all
Three classes is too soon to make a stay/leave decision. Different dojo have different flavors and different strengths. Attrition is a huge consideration and a tedious reality for people in dojo. They may be waiting to see if you stick around, their aloofness becoming a self-fulfilling proposition if you don't. I'd suggest sticking around. The one person who can make it worth your while might not have been in class with you yet.
Folks are often flattered to be asked for help and will usually tell you more than you wanted to know. So asking someone before/after class might help. The trick will be to get them to work with you rather than yammer (hint: Don't yammer at them.)
Funny the schedule/classes make no provisions for beginners...
