Gallus

Apart from a brief sortie out, we stayed at home and put up the decs. We have a new wreath for the front door. The SK, despite having purchased the thing a few weeks back, was unsure about whether to hang it up on the front door. 
Is it a bit gallus, she asked, her voice betraying uncharacteristic uncertainty. 
It’s well gallus I replied, but in a good way. 
Is it? You don’t think it’s, you know, just too gallus?
It’s not too gallus at all, I said. Or if it is, it’s in a knowing way, you know. Besides, it’s from John Lewis.
That seemed to settle it.
