Hello Mike ! Would you like a drink ?   No , thank you . I had too much to drink yesterday evening . I had a bad hangover this morning . My head felt terrible .   Were you celebrating something ?   Yes . It was a friend ’ s birthday party . We drank all kinds of things-beer , wine and spirits . After midnight , we were even drinking cocktails !   It ’ s a bad idea to drink a combination of alcoholic drinks . You should stick with one for the whole evening .   I know , but it was a celebration , you Kwon ? I don ’ t think I ’ Ve see you drunk .
