['I felt really bad about what I did when me and my  brother got new phone cases.', 'Oh my, what did you do?', "Nothing too bad, just that one was basically scuffed up and almost broken but I took the one that wasn't and that just made me feel bad."]
Its okay, hopefully it was not too expensive1
One time I ordered some phone cases for me and my brother. I saw that one of them was really scuffed up so I took the better one and felt bad about it later on since I basically lied to him.
