No, not because her infant’s sunglasses probably cost more than my own.
It’s because she was able to actually PUT sunglasses on her offspring without him instantaneously trying to fling them off. Putting sunglasses on my toddlers is (or was, in the case of the Munchkin) like trying to put a bandanna on a cat. Nice in theory, but horrible in practice. The clawing and yowling effects caused by said accessories are pretty much the same across species. In my family, anyway.
