You must be the holy grail of rohan.
Apart from your egocentrism, what makes you think you have the right to judge anyone?
You're correct in your statement that I do not know these people - but can I help that they're being so shady. Instead, I'll judge on what I do know.
However, in this case I doubt that will make any difference.
People are being judged on a daily basis, the second you meet/see/hear someone new, you judge them.
Anyone denying that, would be only judged a fool or just very naif. Which is as good as a synonym.
Now, put those pumps back where you've got them from. They're not yours to wear, not this time.
