Under control but stepped away anyway

I took a couple beats (AAxx favored in a three way all in pre and top set losing to a bare open ender) and a semi-cooler (jacks full of kings versus kings full of aces). I felt that I was still playing well and made some of the money back but decided that it would be best to just shut down the tables anway. Took down a couple of small pots on my way out. I'm just playing it very conservative to avoid tilting off chips. The tables will be there any time I want and I can just come back later. No need to stay and risk playing less than optimally. Dropped $1.17 in that session. I'll write it off to variance.
