['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.']

My friend was supposed to pick me up to go shopping yesterday. But my friend never showed up.
