My daughter started grade 1 this month and her teacher and I have a daily communication book. Today she wrote something with the title "without delay", but i don't know what it means! Can someone with better Japanese than me please help me by telling me what it says?

This is what she wrote...こうざふりかえのいらいしょ「ゆうびんきょくの」もってきてください。「しきゅう」

thanks in advanced for any replies!
