Let's be honest - the main reason they sneak out so much is because Luisa is their favourite girl and it's the only way they can get her to spent time with them with all her other chores. 💕🐴😘 (Personal headcanon alert, but I'm convinced that in the future Antonio has to mediate arguments between the donkeys over who gets to carry Luisa to the church on her wedding day [yes I did get the idea from that one scene in Mamma Mia 😂] because after all the extra work they've caused over the years, they're making sure their best girl gets her special day. 😝)
