are you ready to go the concert ?   yes . Should we go there by bus so we aren't late ?   actually , why don't we go there by bike ? We could get stuck in traffic if we travel by bus in such hour .   that's true . Cycling is good for our environment , too . Let me just get my helmet then .   is your helmet comfortable ?   not really , but I liked the design , so I got it .   maybe you should think about getting a round helmet ; they're better .
