Facing the Sun
This individual was working outdoors and had a mask on when they suddenly realized they had forgotten to apply sunscreen. Unfortunately, this realization came too late for them to take any action.
As a consequence, the following day they woke up to find their face sunburnt, except for the portion that had been covered by the mask. Due to remaining in the same position for the majority of the day, their sunburn was limited to only one side. Let’s hope they remembered to bring sunscreen for their upcoming shift.
