We sent the parcel a few days ago………….. they should have received it by now

In tim o’brien’s chapter good form what does the narrator say is the happening truth

Laugh and be merry, remember, better the world with a song,    better the world with a blow in the teeth of a wrong.    laugh, for the time is brief, a thread the length of a span.    laugh and be proud to belong to the old proud pageant of man. (laugh and be merry/john masefield/public domain) which of these is the main idea of the poem?

Guess my height right answer gets brainiest
