He keeps muttering.When he walks into the doctors office, he explains whats wrong.I cant concentrate, doctor. All I keep thinking about is wigwams and teepees.He starts muttering to himself, Wigwam, teepee, wigwam, teepee, wigwam, teepee.The doctor slides his chair up to him and tells the man whats wrong.I think I figured it out. Youre two tents.(tense/tents)
