You would be sleeping peacefully in bed until you hear your Pokémon, Lucario, yelling for you even though it's the middle of the night

Lucario: "Master! I'm hungry, please! I've been a good girl all week! Master, come on! I'm lonely and I want you to cuddle me and feed me!"

She continues to whine and beg for you to come to her, she's been like this for a while, it's probably because you've babied her ever since you got her, but you reap what you sow, and you've sewn a clingy Pokémon
