Is the second sentence correct? If so, why do we choose one or another of these collocations for “though”? - I like him, though he makes me angry sometimes. - I like him. He makes me angry sometimes, though. "Though" and "although" are tricky words. I think "although" is better in this case and probably generally, although (!) I can't explain why. There are other ways to express this particular idea, all of which I prefer: I like him but sometimes he makes me angry. I like him although sometimes he makes me angry. I like him even though he sometimes makes me angry. I like him; nonetheless, he sometimes makes me angry. While he sometimes makes me angry, I like him nonetheless. This is probably not much help (although the price is pretty good)!
