Don’t adopt this mentality. It’s too vague and has no point.

I think what they are trying to say is this:

“Guard your friendless, for many take advantage; Set boundaries and remain true to who you are.”

If being friendly is who you are, then it means absolute dog 💩what I or anyone think of it. All that matters is how quickly you leave the presence of those who disrespect your kindness. Stay Friendly
