MEME REFERENCE

Car turning

Use when someone abruptly abandons the sensible path to pursue a much more tempting option.

What it expresses: A last-second swerve reveals which desire overrules the original plan.
Example: You intend to save your evening for chores, then a friend messages 'board games,' so you label the exit ramp accordingly.
When not to use it: A driver changes routes because the road is closed; a necessary detour is not temptation defeating discipline.
