Meredith:
[Roll Eyes] I believe it is up to each individual writer to be willing to hone his craft.

[Frown] Some people are not considerate of others in respect of time. Your time is valuable and I'm glad you put the burden on this lady to get some work done right.

[Cool] Friends will always be friends, critique group or not. There's no need to feel guilty if you decide to move on!

Best wishes!
