Compatibility

When do we become interested in someone?
Does it have to do with compliance to preset ideas and mindsets we have?
Does it have to do with our likes and dislikes?
Or he is simply compatible with our wants?

Which one do you believe in: Compatibility by default or by intent
Compatibility by default is when you naturally are fitting the dress without any trimming but by intent is when either you or the dress has to trim for the two to fit in

I always believed in compatibility by default, it is easy, reliable and irreversible (hopefully); I have faithfully waited all these years for "the one" to come by and free me up from the hassle of walking around with this dress in my hand, looking for the right fit.
Every now and then I have found someone that seems to be fitting, but then after a while I look closer and I see some places are loose, some are tight, combination does not look coherent, and all in all it is a mismatch. What option do I take? Obvious, find a more suitable one.
Today, I was listening to this audio about awareness and conscious living that I heard the click in my head: don't change the one, do not change the dress, do not trim either; look differently, observe closely, be aware and attentive and enjoy it as it is inhuman, imperfect, real but all true
We do not fit, we never will, how do we expect others to do so...
