I’m sorry, it’s my fault
Thank you, it’s all thanks to you
These were words you said out of habit
Even though I knew you were struggling too
You probably think I’m a fool
If I say that things are hard with a crying face
Will it really get better?
If I cry and say it hurts, who will have a harder time?
Everyone will be fine
