Sana and the Bees

Sana gets homework from her teacher to do a presentation about bees. She went to her dad's friend's farm to find out more about bees to be able to do her presentation. Sana had a lot of fun in the farm and she also ended up getting a gift from her dad's friend: it was bees. Sana went home excited and took good care of the bees. But after few months she visited her dad's friend again.
