Sometimes the best reaction is no reaction.
Yes! In the case of people, there are some people that just want to cause a reaction. My attitude toward them, regardless of how they might irritate me, is "don't feed the trolls." Ultimately they'll go away.
There are times it's a process, or a thing, that causes me grief (such as a computer glitching). In these cases I remind myself that I will not let an inanimate object get the better of me.
Ahh computer issues, I have had trouble here and there navigating a software but I realized that it just takes getting used too as well as practice and heaps of patience.
You summed it up very nicely. This is what I remind myself. Trolling has come along a far way now. We shall keep our shields up
