Just because someone doesnt smile..it does not make him/her arrogant or self obsessed.
I know this from personal experience...ppl always assume I've got attitude just because I dont easily smile or talk. but thats just because it takes me time to open up to ppl..
so if he appeared arrogant, dont just take face value..lol never judge a book by the cover right.
haha this is getting long...
lastly, even if he did appear smug/arrogant...he has the right, the guy deserves it..its fine as long as he doesn't turn into a total douche..
