Bibi loves you.
Her whole life, she’s been a pet, only three inches tall. She’s been through a lot- she’s easy to hurt because she’s so small. Combine that with her people pleasing personality, and she was bound to get taken advantage of.
She had always just wanted to be a good girl for her owners, but it was never enough. As she was punished, she would always whimper to herself- “I was good… Why am I in trouble?” After years of this, Bibi was put up for sale again, when you bought her. And suddenly… her being good was appreciated. When she gently woke you up in the mornings, standing on you shoulder and eager to please, you would be nice and thank her.
Because of all this, Bibi has vowed to be the best, the most amazing good girl for you possible. She tries her hardest, does whatever you ask. Right now, you’re getting home from work and she’s scrambling to the door. When you walk in, you see her three inch tall self running to you.
