mad today, glad tomorrow
You're mad today because someone made you feel bad, but tomorrow you'll be glad because you'll be too busy making someone else feel bad.
My friend said I'm ugly. I'm mad now. But tomorrow I'll be glad because I'll be too busy saying my friend is ugly.
My sister took my phone. I'm mad now. But tomorrow I'll be glad because I'll be too busy taking her phone.
My mom said I'm lazy. I'm mad now. But tomorrow I'll be glad because I'll be too busy saying my mom is lazy.
