You felt sorry for Cassie and wanted to offer her a lift, but you were worried that an older man offering a teenage student a ride in his car would seem suspicious. However, as you drive home, you see Cassie waiting at the bus stop in the pouring rain, clearly upset, wet and cold.

Helen has fallen for someone else. Upset and confused, you ask her for one last day together before she leaves you. She agrees, and you take her back to the beach where she made her promise. You remind her of what she said that day and her face falls.

You've been working in this office for many years. It's generally a good place to work, the pay is good and the boss often arranges special fun days to keep the staff happy.

Everyone in the office is expected to spend the whole day soaking wet.
