The advantage of love at first sight is that it delays a second sight.

— Barney, Natalie Clifford

I do not think that what is called Love at first sight is so great an absurdity as it is sometimes imagined to be. We generally make up our minds beforehand to the sort of person we should like, grave or gay, black, brown, or fair; with golden tresses or raven locks; -- and when we meet with a complete example of the qualities we admire, the bargain is soon struck.

— Hazlitt, William

Where both deliberate, the love is slight: Who ever lov'd, that lov'd not at first sight?

— Marlowe, Christopher
