Hey Everybody! How's your weekend going? I'm doing terrific.

Anyways, I was wondering about this concept of cis passing. I've heard the term before and I was wondering what it meant to everyone here. It seems like when people say that someone is cis passing it means that they pass well enough that most people they interact with wouldn't know they are trans without being told. Does that sound about right?
I want to pass well enough that I could have relationships with people without them knowing I'm trans. I've passed well enough 'at a glance' and 'at a distance' for a while, but it seems like when I interact with people closely they always seem to know sooner or later that I am transgender. Sometimes I feel guilty about this because I shouldn't be ashamed of being trans and even though I know that wanting to pass to make your life easier isn't something to feel guilty about I know the real reason I want to pass like that is because I
am ashamed of being trans (at least a little).
Anyways, I talked to my sister about this and she--I love her, but she's so critical sometimes--tells me that she doesn't think I should get any facial surgeries and she also said that I'm assuming that I'm not passing when I actually probably am, and also that I have body dysmorphia or whatever. I haven't been misgendered since Christmas (this was with family who are probably used to thinking of me as a guy, so that could be why...) and I was wondering if...
Do I have the right definition of what 'cis passing' means?
Do I pass for cis right now?

Will FFS push me over the edge? So to speak?
What does everyone think?
