Not sure if you've been following Brett the past couple of months, but if not I'll get you caught up real quick.
He gave up his smartphone at the beginning of the year so he could live more in the "now" instead of being so involved in social media and what's happening there.
He uses a flip phone and has been taking pictures with a Polaroid camera which he then mails the pictures to friends and family.
From his other most recent post which you can also see below, it appears that he is going thru some things. Trying to find himself and to an extent be happy again. It does look like he's enjoying himself from the little we've been getting which is great! Definitely miss seeing him post about his dog all the time though. That does suck lol.
