Cousin's Day honors your Aunt and Uncle's kids. They are those great kids who are likely close to your age, and endure the countless family get togethers with you. If it wasn't for cousins, these family events would be much, much longer.
This is a great day for your cousins. Now, hold on a minute. If you have cousins, that means your cousins have cousins. And, that's you! Therefore, today is your day,too.
Celebrating should be nothing but fun. Get together with your cousins. Hang out, just chill, or do anything you want to do...... as long as its a fun time spent with your cousins.
