About a year ago, there was a boycott on the Loblaws supermarket chain in protest of their boasting record profits at a time when grocery inflation was out of control. It lasted about a month before kind of fizzling out.
But I think by comparison, this buy Canadian movement has legs. It's a major nationwide shift in people's spending habits. And the key word here may be habits. Let's say for argument's sake that after 4 years of Trump, a new administration comes in and repeals all the tariffs. By that time, people will have settled into alternate brands across a wide range of consumer goods, and it may be difficult to convince them to switch back again. There's a certain inertia in human behaviour. So the effects of this could potentially go on quite a bit longer than the tariff war.
For me, I think it's whatever face I make when I'm in the zone. I'm not really aware of what I look like or contrive to look a certain way. But if I crack a smile, that's a pretty good tell that I goofed up somewhere.
One time I was playing a Robbie Burns event where we were all encouraged to wear kilts. I made the mistake of putting my phone in the sporran (a kind of purse that hangs right over your crotch) and it started vibrating incessantly. I can't even imagine the faces I was making that night!
