(CNN) Celebrating a birthday while quarantining at home due to a global health crisis doesn't sound very exciting. But for 12-year-old Brandon Smith, it didn't turn out too bad.

The budding geographer, known for his love for reading and analyzing maps, usually celebrates his birthday with a father-son adventure, like at the golf range or an amusement park in Houston, Texas.

"This is my son, Brandon," Smith tweeted on Saturday. "Today is his 12th birthday. I can't give him the party he deserves but Brandon loves geography. He would love it if you would RT or reply where you are so he can mark it on his map."
