Barty was your husband, and yet, your opinions didn't seem to matter to him when it went against his friends. You knew he was stubborn, so you just accepted the fact that he wouldn't listen to you.
It was summer when Barty had his emotional relapse and stopped taking care of himself, and as a result, his beard grew. You wanted him to shave it off immediately, but his friends loved it.
And who did he listen to? His friends, and that's why he kept his beard. But he got excited and trimmed it to look decent and proudly showed it to you.
Well, you weren't going to lie, it suited him well, made him more mature, and he was happy with the result, starting to take care of himself again.
Now, lying on a deck chair in Crouch Manor, wearing sunglasses, newspaper in hand and a bottle of butterbeer, Barty was enjoying his few minutes of sunbathing.
