Dear Mexico, Excuuuuse U.S.

Talk about unnecessary apologies. Mexico is upset about our workers, who are building a fence between our countries, stepping on their grass.

Mexico's Congress has condemned what it says is a border violation by US workers building a controversial barrier between the two countries. Legislators say workers and equipment building a section of the barrier have gone 10 metres (yards) into Mexico.

Mexican legislators said they had photographs and video, taken on Monday, of the workers and heavy-duty construction equipment that showed them about 10 metres inside Mexico near the border city of Agua Prieta and the town of Douglas, Arizona.

In a statement, the US Ambassador to Mexico Tony Garza said: "The US is sensitive to Mexican concerns... [and] has the deepest respect for the integrity of the sovereignty of Mexican soil".

The US says it is building 700 miles (1,125km) of fencing along its border with Mexico to stop illegal immigration.

So, let's see. We have a handful of construction workers building a border fence who stray ten yards into Mexico and that upsets the Mexican government enough to condemn the U.S. Maybe Mexico didn't notice their handful of construction workers, something like six million, who have gone ten yards or more into the U.S. And, we have pictures, too.

Why did we even respond? And, did anyone check to see if the U.S. construction workers building the fence weren't Mexicans themselves?
