 Person1:      You had been walking for 6 hours , isn ’ t that boring ?

At noon , we had the most special winter picnic outside . Fortunately , we got it all on a video tape . You must come with us next time . I bet you will love it .  
 Person1:      Well . You know I hate walking , but I can ’ t wait to see your guys ’ video .
