Andy hated mornings, which really meany anytime that he got up at - if it was before 1 in the afternoon he felt that he'd gotten up too early, but anything after that and he felt like he'd missed out, wasted the day. He compromised with a healthy hate for waking up in general, while the sleeping itself was something he loved.
Regardless, waking up with the sudden full and bony weight of his best friend ambushing him out of nowhere would have made him hate waking up anyway.
"Fucking Merlin!" he yelped as he woke up, one elbow coming to jab away whatever it was that was attacking him, his other reaching for his wand and, luckily, not reaching it before he realised that it was just Jack being evil and calmed himself back down with a groan. "You're a dick." he said with feeling.
