Do I know U-hehhh

I sent a message to a former officemate of mine. Guess what’s her reply? She said to me, DO I KNOW YOU! Huh! Do you know me huh! Well, I opted not to reply since she’s not worth my time. My name is clear there and she said those words. Well, who cares about her? Do you care for a friend like that? For me, I don’t care! And do I know her either! We-he-he-he!
