According to folklore, when intruders disturb a rattlesnake, the first passerby merely irritates the viper. The second passerby becomes truly annoying. The third in rapid succession, though, becomes just too much. And that’s the one the snake strikes.
I think many of us humans have days like that. When we erupt – or someone blows up at us – it’s often far out of proportion to the provocation. What you see merely reflects the third offense or offender – the one that triggers defensive action.
Either way, don’t take it too personally.

I wonder if that is what the bee was thinking the other day as i was hanging washing out – one shake – ok, two shakes – getting annoyed and three shakes – go you!!
