The bottle was her. The faucet was her heart. The water was him along with all the memories.
If faucets have handles that controls the water, whether it should come out hot or cold, or just outright close it and cut off the running water. She wished her heart had one. She wished she could make it stop but she didn't know how or where to turn it off. Or maybe the handle was already broken and irreparable just like her. Try as she may to block it with her hands, the pressure was too strong for her to handle. The water went past her hands and splashed all over. Submerging everything within.
