Its not really in the vein of the conversation, but there is nothing worse than an elderly parent talking to you after having coffee with their friends.
"Did you know that there is no point in working Overtime because the government takes it all? You're working for free! Oh! And that CPP is non-taxable because you already paid tax on it!!!"
None of those things are true.
What do they put in that coffee at the Casino? I might have to get some.
