I'm positive that you're negative

[Lightspeed]

My group know that I am upbeat 99% of the time and for the other 1% they support my grumpiness by becoming more positive themselves.

Problems of morale in the group only occur when we are all completely worn out, and our emotional energy reserves at zero. Thankfully we can recognise when this is happening and have coping behaviours as we know it to be a very rare and short lived event.
