No Attention to Detail
Architects spend several years in architect school to learn what it takes to become an architect. One of the first things an architect learns is to pay attention to detail. That’s like Architect 101, so you’d think that all architects would know how to spot minute mistakes.
Wait, the person who made this mistake wasn’t the architect, it was the construction worker! Aren’t construction workers supposed to stop and assess the situation before moving forward? These guys clearly saw that these corners didn’t align and thought, “Whatever, the homeowner won’t notice.” How wrong you were, buddy. Now, the entire world knows about your clumsy construction skills.
