…has to be…
…the oddest question ever.
None the less, yes, I can flare my nostrils.
At one time, it was a signal my mother used to use whenever I was eating something I loathed with a great passion. Such as turnips or parsnips. That great loathing has continued on to this very day. Other foods that I used to flare my nostrils at while eating consisted of; long green beans, peas, pumpkin, beets, beet greens, broccoli, cauliflower, and oatmeal.
I don’t loathe those foods as much (with perhaps the exception of beets and beet greens, though I will eat them), so therefore I don’t flare my nostrils up as much as I used to.
Parsnips and turnips however, you still loathe greatly.
