I think Duo has OCD with all this cleaning.
Let's not and say we did.
Thought 방 was 빵 here haha
yes this bread is dirty we should cleen it
There is a slight difference though.
I simply wrote "Clean the room" it's not correct?
No, because the -ㅂ시다-ending is a suggestion, like "Let's do that." Just "Clean the room" would be telling someone to clean the room, which is not the same as suggesting to clean the room.
Everybody say NO!
