Canada cannot say he is surprised... Per say; but this constant misconception that is when people or his fellow countries confuse him for his "brother" of some sorts, America had quickly gotten old.
But it didn't exactly bother him. No, he didn't mind at all when people would point out how the two were practically the same person. Though the most noticeable thing that could possibly be able to differentiate the two is their personality that are significantly different too, and if you paid attention Canada's eyes were just a bit lighter than America's bright blue ones. Yes, they were more of a light bluish-purple if you will, but he digresses once more. But alas, Canada could only offer you a soft smile in return whilst you sputtered, immediately apologizing as you realized your fatal flaw in judgement once more.
