Unappreciated

Most days I am rudely awoken very early in the morning.  If I do not wake immediately, without hesitation, you complain about me. Waking up without being a little tired is too much to ask of a human, so why hold me accountable?  Although I am tired, i still do my job.  As I carry you along, you talk other people, eat, or look at your phone.  I am never appreciated.  Even though these various activities can harm me physically, you do them anyway. I guess they are more important than me.  As we arrive at wherever it is we always go, i finally get to rest.  Later in the afternoon you wake me up again and we return home. Like always, you pay no attention to me. But what would you do without me?
