I was so tired after a week-long retreat that I skipped going out lunch with my class. As D told me, this is the irony of retreat.
So I joined his cg for a quick lunch and got home. Kudos to J for sending me home. I think fatigued affected my temperament. Was rather impatient and easily agitated. Although my fuse was pretty short, thankfully it did not blew.
There was once I nearly reacted to an unwarranted self-exclamation. Fortunately, rationality gripped me and I kept my cool and let it pass.
On hindsight, was glad I did. It would have been terrible and intimidating for an incident that is otherwise so petty.
