Are the following answers natural? Can we have short answers like these in English? Or is there misunderstanding if we answer this way?
A: Would you like some coffee?
B: Thanks, I did. / Thanks , I already did. (Instead of I drank some.)
A: (Mother to the son) Tidy up you room.
B: I did, mom. (Instead of I tidied it up.)
A: Please don't forget to buy some bread on your way home.
B: I have. (Instead of I have already bought.)
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
