As much as I am of Chinese descent, I grew up reading and writing, thinking and dreaming in English. (I would admit without any qualms that I am a Banana Chinese - that is, outside yellow but inside white.) But, there are these 2 sets of verb-noun word groups that totally irk me: they are respond/response and prove/proof - I always have to think a little harder than usual to figure out which is which, i.e. which is the noun and which is the verb. If I do not think about it, more often than not, I will use the wrong one. And that irritates me.
