about four o'clock
Suppose we go and take a ride in the park this afternoon . It 's a great day . '' `` I do n't mind riding in the park for a while after dinner . I 've got a date about four o'clock . But I 'm not a monomaniac , Nelly , and nothing 's getting on my nerves . I never felt better or happier in my life . I feel as if I 'd been blind always , been sort of groping my way , and had just got my eyes open to see what a wonderful thing life really is . ''
