My grandpa is not anyone else. He watched silently for a week to understand the environment he explained like an anthropologist. Then one Thursday a kid posted, Guys, is depreciation on the accounting exam? I'm lost. My grandpa owned a general store.

00:36

Speaker A

He learned accounting over 40 years behind the counter. He couldn't resist. Depreciation always comes up, son, on the exam and in life. Study the straight line method first. That's what professors like. Sincerely, Osvaldo. The group froze. Who's Osvaldo? That number

Speaker A

And so began the Osvaldo era. He explains accounting with store examples. Inventory is like cheese. Buy the wrong stuff and you'll watch it rot. He accidentally started a catchphrase. He signs everything Sincerely, Osvaldo. Now all 43 kids do it. Sincerely, Mariana.

01:31

Speaker A

It became the group's dialect. He scolds them about attendance. Nobody has confirmed for Saturday's group project.

01:36

Speaker A

In my day we call that bad manners. Sincerely, Osvaldo. Suddenly everyone says they'll be there Saturday. The man became the class's collective superego.

01:46

Speaker A

At semester's end the class officially invited him to their barbecue. My grandpa went in a dress shirt. He brought my grandmother and 4 lb of good sausage because students buy cheap meat.

01:57

Speaker A

He was the star. He told stories, gave career advice, and danced with grandma. The kids even switched from Brazilian funk to a slow song just for them.

Speaker A

There's a photo of him in borrowed sunglasses, surrounded by 20 students striking the same pose. The caption, Dad of the Semester. And here's what nobody expected. Three students passed accounting with his help. One posted their grade in the chat. Got an 85

on the exam. They invited my grandpa to give a talk, Accounting in Practice, 40 years behind the counter. He's preparing slides. My cousin's teaching him now.

He's already chosen his opening slide. Sincerely, Osvaldo. Next semester is their last before graduation. They've already told him, you're coming with us.

02:52
