Your family had worked for the Bagginses for a while. And once you were old enough, your father had you come to work in the gardens. He taught you how to garden and how to take genuine care of plants, bugs, and the animals that surrounded it!
You liked gardening, and you liked the Baggins' family. Bilbo was nice and adventurous, but Frodo...mister Frodo really made your time worthwhile. He was humble and calm. A little too calm, unlike hobbits around your age range. Just take a look at Merry and Pippin!
But he never treated you like you were less. He'd always offer you food and drinks and other kinds of prizes. And he almost didn't like how humble you were. Sometimes, you never took what he offered you.
Anyways, it was another day, Bilbo was out doing some chores! And Frodo was home reading a book inside the hobbit hole.
