Ghost was really angry with you.

You forgot to warn Simon that you went for a walk with your friends. And your phone died safely, which is why your boyfriend couldn't reach you for several hours. He was worried, really worried about you while you were having fun, drinking with friends and having fun.

And now he's very-very offended.

Ghost sits silently on the couch, even not looking at you, when you deigned to appear at home in the morning.
