There's something I've been pondering/observing for a few months, and that's the tendency for people to say things like "everyone sometimes feels x" or "no-one gets through that without doing y" or even "anyone who says they've never z is lying" when their intention is merely to reassure someone that x, y, or z is an acceptable/appropriate/understandable reaction to a given situation.
It bugs me partly just because I don't believe such generalisations can ever be true*, and more specifically because it makes me feel like it's denying the experience of those to whom it doesn't apply. I happen to be someone with good self-esteem, whose life to date has been perhaps unusually easy and contented; I recognise that this makes me very lucky, but I also resent encountering statements like those in the first paragraph when they imply that people like me don't exist.
But it also bugs me because of the implication that 'universal' (or at least 'very common') is equivalent to 'acceptable/appropriate/understandable'.
