Is it so difficult?

Is it difficult to say the words? Is it so hard?
"I'm sorry", "Thank you", and "I love you".
Was it so difficult to say?
Without saying anything, do not think;
'He'll know what I want to say, whether I said or not'.
It's impossible to let him know about your heart or feeling without expressing yours.
Now, it's time to express what you want to say.
"I'm sorry", "thank you", and "I love you".
