Everything changes

I don't know what is the real gravity of this but I don't like...
It's crazy, sad, tired... I think it's this. I'm too tired.
What happened?
I knew you, but you changed and now you are so strange to me. WHY?
I'm afraid of to ask because i've got afraid of the answer.
Do you know the answer?
Maybe us need a little patience or time.

Some words are wrong, but it's alright. Sometimes our words are wrong too. So, i don't care.
