It's not that I dun care

Why on earth does people like to make me look bad. While going home I saw an old lady. She was having a hard time carrying her trolley down the stairs, so I wanted to help her with it, but a middle-aged lady approached her first. However, the old lady rejected her aid. So I was standing behind her, knowing that she will reject my offer. But it doesn't feel right for me to overtake her, so I was waiting behind. Another middle-aged lady walked pass and saw me, giving an expression like " Why isn't he helping ". SIGH.
