Despite what we might think, animals remember us and the kindness we show them - and this grateful wallaby is the best example of that.
Reddit user Retaboop, who has helped raise wallabies in need for six years in Australia, recently gave the internet all sorts of feels when she posted a picture of an orphaned wallaby that she had raised - and who had now come back to visit with her baby in tow.
Retaboop took in the wallaby, Mirabooka, after her mother was hit by a car and killed when she was only 5 months old. She raised the sweet wallaby, along with some foster brothers, until she was old enough to go back out on her own.
The thankful wallaby comes back for frequent visits, and even knocks on the door when she wants to come in. The most polite wallaby ever! At one point Mirabooka disappeared for a few weeks ... and came back with a boyfriend, and soon a baby of her own!
"It's been pretty special watching him grow from a tiny pink thing to what he is now. She's a good mum," Retaboop commented on Reddit. The baby's name is Rookie, which works with his mom's nickname Bookie.
