Earlier quoted context omitted.
Parents and siblings. And that actually brings up an entirely other privilege I had at that time. When I first got my job at the movie theater, I was asked by nearly every floor employee how many kids I had. I was one of only a handful who were yet to have children, despite all of us being ~18-26. I can't guess how restricted I would have been in my mobility if I had children to think of at that time.
Oh god, take this 'privilege' stuff back to Tumblr. Not having kids isn't privilege, it's choice. Edit because I don't want this comment to come off too aggressively: you sullied a perfectly nice set of comments and truly interesting anecdote about your life by discounting it as privilege. Since when are wise choices privilege?
Re: your edit, it's not the choices that are privilege, but all too often, the opportunity even to make them. As a white male, I have choices, and opportunities to make them, that women and non-white people simply don't. That's privilege: not what you do with the choices you do have, but the choices you have available to you.
