There is no turning back now
Maria’s plan would be carried out at any time now. She envisioned the girl’s reaction. She might scream or shout. She might cry, or she might whirl around and punch Maria in the face. That last thought made Maria tremble, but there was no turning back now.
The last straw
The girl in front of Maria shifted unexpectedly. She sat up a little higher, tipping her hair tips over Maria’s cup. Maria tried to move forward, but she was too slow. The cup tipped over, spilling the thin layer of water all over the place. This was the breaking point.
