Nathan sighed 'great, now I feel like crap' he said to himself "no, no. You came all this way, so the least I can do is hear you out. I wasn't trying to scare you away or anything like that" he told her "I was only trying to explain why I seemed so grumpy. As bothersome as this day is becoming, I'd feel a lot worse if I just turned you away without at the very least giving you a chance to talk. Again, I'm real sorry about this, but you didn't manage to catch me at my best" he continued, trying to make her feel more at ease
