In Finland, it is pretty easy to upset someone's frame of mind, all you need to do is change the schedule, be a little late, or a little early, shift the plan. They are a culture of planners and things tend to work, but when the schedule changes, they are a bit like ants with a stick across their walking path. But, there is a cost to be the one to disrupt the path too, as the unstructured person, the flaky person, is seen as unreliable, and can't be fully trusted.
The Finns are right about this. I, too, find anyone who changes plans untrustworthy unless there's a life-threatening emergency. Selfish, irresponsible people harm those around them in the long run. There are those who simply can't even communicate a change of plan, and I can't think of anything to say about them anyway. It's tantamount to a small-scale scam.
The photos look amazing. You're taking more impressive photos every day. Autumn, in particular, offers wonderful poses. Don't miss out :)
The thing is though, it takes all types. Quite often, the unstructured, messy, late people - are also the ones that create the most beauty in the world. The artists and the musicians and the like. We have an interesting dynamic as humans, as our nature can be quite different, but still adds value to the whole.
