I started Yoga back 7 months ago when all this drama started and it has been a life saver. I am so glad you liked it. I love it - I feel so much better after I am done.
I hope others weigh in because I am struggling with trying to be cordial, too (i.e. not too friendly but not cold either). However, I think your plan of waiting until tomorrow to text back and say something like "yes, enjoyed it" seems great IMHO.
