It will never really seem youthful to me even though I've met several young Lillians. My stepfather's mother is named Lillian and she's 94 (and sharp as a tack) and the name just feels like it's every one of those 94 years old itself.
But it's at least got more spine than Lily.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
