I can feel your pain
When you tell someone you understand exactly what they're going through, like when they're stuck in traffic and you're like 'Bro, I’ve been stuck in traffic so long my feet turned into roadkill.'
My friend got stuck in traffic for three hours and I said, 'I can feel your pain, I once got stuck behind a school bus for two hours and I was ready to scream.'
My sister got stuck in a long line at the grocery store and I told her, 'I can feel your pain, I once waited in line for three hours and I turned into a human statue.'
My dad got stuck in traffic during a thunderstorm and I said, 'I can feel your pain, I once got stuck in traffic and it rained so hard I thought I was going to drown in my car.'
