Your post might not be unkind, petra, but some, I’m afraid, come across as such in my opinion.
Yes, of course there are dreadful things going on in this world of ours so that it might seem as if a worry about the positioning of plates is not something to get upset about; but the point is, for the OP, it was something to get upset about, and for all we know, it might have been the last straw for her, as we don’t know what she is coping with in her life. For goodness sake, a little kindness wouldn’t go amiss, surely, and if all you can think of is a reply along the lines of a fuss about nothing, or there are worse things in the world to worry about, then perhaps it might be kinder to keep those remarks to yourself, because for that OP, it is something to worry about.
I think Monica has summed it up well.
