My cat always wakes me up. He has a built-in clock that tells him when it's time for me to get up.
With a vibrating phone and a blaring radio i wake up the whole house ..
my alarm on my cell phone
i wake up myself using the alarm clock. :)
I wake up myself.
I wake up without an alarm clock, it doesn't matter what time I go to bed. For some reason I know when it's time to get up.
I have an alarm clock.
