I am saying it is wrong to think emotional responses are wrong. If a thing bothers you and makes you feel in a particular way then you need not be ashamed.
And calling individuals whiners, or foolish for feeling, or anything other than a living, breathing being that can feel, is wrong.
You think someone stupid for complaining about the length of their tea towels, by all means, think them stupid! Only let them have space to speak of their complaints rather than telling them it is unimportant. Aye, it is not particularly life threatening, but you do not know their experiences.
