I had been expecting my friend to pick m e up for a shopping trip yesterday. Unfortunatley my friend never actually showed up.
Sorry to hear that. Were they busy or did they forget?
She claims to have had something unexpectdly come up. I think she just forgot. She often spaces out.
You should not rely on her next  time. She seems unreliable! 
That's probably a good idea. I keep forgetting though.
