Grit can be a good thing.
Grittiness in particular can be a very good thing, particularly if the roads are icy. It's also good if it's related to a movie.
On the flip side, grittiness can be bad if it's found in food, like a flapjack or salad.
And in this case, on this particular occasion, it's in my flapjack.
Other than that, the flapjack would be very nice; nicely sticky and oaty.
