changes 8.0: last minute switch ups

Every Friday I take a kick ass Pilates class - trying my best to never miss it. It's been a constant in my life for awhile and while I have both love and dread relationship with it, the good outweighs the pain in the end. 
Today I raced to class, set up my mat, and a sub walked in. I'd taken her class before and it wasn't what I was looking forward to. Before I even had time to process what to do, I left. 
Walked out. 
Grabbed my bag and skedaddled. 
I didn't want to hurt her feelings so I slipped out as she walked past. 
I then wandered over to my yoga studio, took an hour and a half class, got to hear a stunning version of Little Wing, and dissolved into one of the best shivasanas ever. 
Unexpected change. 
A delightful outcome. 
Not getting caught up in expectations or disappointment. 
Good lesson to hold onto.
