pples whose lives have crossed

It pains me to remember how a person I once knew had certain fixated ideas and assumptions about me, and made a pass at me, as well as an indecent proposition. And this person was dating a friend of mine back then.

It pains me to remember how a person I once knew o/d on drugs and left the world just like that.

It pains me to remember how a person I now know is "trapped" in a verbally and physically abusive relationship, without seeming to let it go.

It pains me to remember...

Is this the same for anyone?
