You ask a tripping companion if "your dials are pupilated". I had a first time tripper on 4-ho-mipt ask me this years ago. I was already on 28mg, and though trying not to be judgemental or condescending, started laughing so hard that I had tears running down my face and abdominal muscle cramps for several minutes afterward. He was really offended in the moment, but definitely saw the humor in his query after coming down.
Edit: I just realized the aforementioned individual was (and possibly still is a BL'er). Hey R, if you're still on BL and read this post, please do not disclose my identity. I already had to abandon my original, long running, account in 2013 after my identity was compromised. I really prefer not to go through that shit again. If you do read this shoot me a pm, it'd be cool to hang out again!
