A state of mind
A state of mind is when you feel like everything is going great, but deep down you know it’s all just temporary and you’re probably gonna crash soon.
I was in a state of mind during my birthday party because I was having so much fun, but I knew I’d be sad when it was over.
My friend was in a state of mind because she was doing really well in school, but she knew she’d probably fail the next test.
My dog was in a state of mind because he was eating all the treats, but he knew he’d probably get in trouble later.
