If she found a kangaroo I would say SHE found a kangaroo that followed HER home and now it is HERS, but I can't say that... 'cause she found an aardvark.
Now I could say that Rafaela Gabriella and Rufus Xavier Sarsaparilla and Albert Andreas Armadillo found an aardvark, a kangaroo and a rhinoceros. And now that aardvark and that kangaroo and that rhinoceros belong respectfully to: Rafaela Gabriella Sarsaparilla and Rufus Xavier Sasparilla and Albert Andreas Armadillo. *whew!* Because of pronouns I can say, in this way: WE found THEM and THEY found US and now THEY are OURS and WE're so happy! Thank you Pronouns!
