You’re trying to fix him. He hated you, so you impressed him until he treated you fine. After 4 years he opened up about one small thing, showing progress.

One day he was doing little hops on his cot while sitting down, zoned out. He had small energy bursts or zoomies sometimes.

You hugged him. He stayed quiet. He eventually gave you a little head pat.

“Good bo-!” You were about to say while holding up a cookie, like he’s a puppy.

But he put his finger on your mask/lips, shushing you.
