i do, often, think of that quote from wislawa szymborska talking about love and the inexplicability of some of it. "great love is never justified" etc. and it truly isn't. and thank god for that.
"We’re dealing here with the phenomenon of great love. Detached observers always ask in such cases: “So what does she (he) see in him (her)?” Such questions are best left in peace: great love is never justified. It’s like the little tree that springs up in some inexplicable fashion on the side of a cliff: where are its roots, what does it feed on, what miracle produces those green leaves? But it does exist and it really is green—clearly, then, it’s getting whatever it needs to survive."
