one of the questions that spun off from discussions with tim today was:

how do you bring love where there is none?
(i'll spin off more questions from here)
is there really no love? or is it a lack of expression?
perhaps the lack of expression arises from how love can sometimes be very trying, and tiring because it involves the giving of yourself, and maybe sometimes even the giving up of certian "rights", where you go "im supposed to have this, you're supposed to do this, but.. it's ok. i'll let you have it"

would trust lead to love?
how do you build a trust with someone?
what would trust be based on?

time for bed. before the questions start keeping me awake.
