You handled it almost right.
You needed to laugh hysterically and point at your “friend.”
Breathlessly struggling to talk, gasp out “thats Clinton’s law, still being enforced - just like under Obama “ “Oh my God your killing me here -Trump’s policy is to not let them place one foot on American soil.”
Every time your rude “friend” attempts to deny whose policy this is, burst out laughing and pointing. Throw in “and they gave you a degree” if your “friend “has one.
It is important not to allow your so called “friend” to retain any semblance of dignity if they are attempting to assign blame wrongly. This is a general point.
You can’t lose a friend as things stand. They have already chosen to make themself only a “friend.”
I’ve been trying to find the citation that ties this all to bjc.
