Chances are (and I'm up for being corrected on this). The bears are being culled to maintain population levels.
In all areas of the world, human interaction with nature means we've upset the usual ecosystem balance. We've moved predator/prey ecosystems, we've changed their sizes and we've decided there are big areas we just don't want the predators. Culling/management is necessary to minimise our further impact.
These bears are going to be shot with or without the furs being used. They're not being killed so someone can have the fancy hats.
"being tired" is a legitimate reason to not want to hang out, it is also an easy excuse with no descernable evidence. Used once it's believable, used lots of times it starts to "feel" like a fake excuse or even a lie.
If your friend thinks you complain about being tired a lot, they are (very likely) trying to say that you're not putting the effort into the friendship they believe they deserve out if you.
As has been said in other comments, it might help to give examples of times where you'll be less tired. Or just invite that friend out at those times.
A friendship dies take effort from both people to maintain. Breaking your cosy sofa time is effort, but if the friend means enough to you then you will sometimes make that effort to see them.
