i would agree with funky that nothing human is truly unconditional (ok, my words, not funky's), but i have proven myself capable of advocating, over the years, that my friends and loved ones do things that are explicitly not what i want, because it seems like it would work better for them. it surprises me every time i do it, which is why i remember, although i don't talk about it at the time.
mostly i am suspicious of anyone talking about love; much like spirituality, it covers so much ground, and so much of that ground is ineffable (lol wut?), that talking about it makes me itchy. it is nice to think about the different words in other languages for the thing that to english-speakers gets lumped in a single term (among tons of other meaning not even mentioned here), but to actually shift the meanings in some real way i think is beyond people who are mono-lingual (eek. this gets us into a whole different conversation, so never mind).
i will just end that i think it's an awesome thing to commit to something that feels bigger than oneself, to be swept away, hildegard of bingen-style. (and yes, christianity has owned a lot of the examples i would know about, but gdmt...)
