Billy , you don ’ t look too well . Maybe you should take the day off school .   But Mom ! Today we ’ re playing football ! I love football !   You ’ Ve got a fever and playing football isn ’ t a good idea for a boy with a fever . What ’ s that on your arm ?   I don ’ t know . It was there when I woke up this morning .   It ’ s rash . I ’ d better take you to see the doctor . How did you get that bruise on your leg ?   I bashed it against the chair in my room .   Does it hurt ?   A little , but not much .   Here . Put this wet towel on your face to keep your temperature down . I ’ ll take you to the doctor ’ s after breakfast .   If I ’ m better this afternoon , can I go to school ?   If you are better , but I doubt you will be .
