`` You 're both dears , are n't they , Tommy ? You must come and have tea at the hospital any day : just walk in . Mine 's Ward 3 . Come about four o'clock , and you 'll find me any day this week , Tommy 's opposite . There 's usually a crush at tea , but you must come . By the way , where 's your camp ? Are n't you going heaps out of your way ?
