. His family were right wing extremist where grandpa was a member of Slovak Nazi guard or SS unit during WWII.
Dear god Kaik, am I right in thinking you are Czech? Hungarian? Either way it doesn't bare thinking about what Nazi Grandpa got up to during WW2. Not to be upsetting anyone but the local Nazi sympathizers - Hungarian Arrow cross? the French the Ukrainians the Lithuanians were terrible ! were the Czech Nazis the same? Oh my god Liddice! Anyway - the locals always seemed to be so much worse than the Germans...oh so willing to do their dirty work. You were right to run a mile!!!
Getting back to the OP I had one, not weird exactly ... a young- ish girl whose boyfriend came to sit in. He would offer drinks..tea whatever, and say " bob's biscuits" but not once, like 20 times!. Then he would say it a couple more times when the study began listen a while ..say it again and leave ....now I look back he may have had Tourettes syndrome.
Bobs biscuits!!! The funny thing is I can't stop saying it myself now sometimes when I give out biscuits! Its stuck in my head! Instead of me passing him a meme he's given me one!
