I'm actually not a Bitcoin salesman. I'd rather it go like this:

Newbie: Hey don't you have Bitcoin? Me: Yes and I believe in it quite strongly Newbie: Should I buy Bitcoin? Me: No. You don't understand why its important. You'll buy a bunch of scam tokens thinking they have some similarity to Bitcoin (they don't) you'll get rekt and then you'll blame me for it all. So you shouldn't buy Bitcoin.
