(and yes, I believe there are some that have an extra past life wallop to them)
are always about changing your "frames of reference"
without them, your path goes along on its own trajectory
and then, poof, someons shows up, causes a "reaction"
and sets you off on a different course, with a completely different set of eyeballs
always a blessing -- no matter how they appear, no matter what the disruption
some relationships change you more than others -- they are always, ultimately, a gift
. . . even if the gift isn't "revealed" until they pass and the dust settles
