In answer to why I'm not answering your calls

We met
We talked
You called me Sunday morning at 8:30
We had a cool conversation
You said you wanted to take me to breakfast lunch whatever
I told you I was only available until 5 'cause I had plans after that
At 9:30 you said you were getting in the shower and getting dressed
You said you had an errand to run and then we would go

(Where it goes south)

At 11:30 when I didn't hear from you I made other plans
At 4:00 when you called you didn't leave a voice message
You left me a text that said
Hey babe, what's up?
