你送她回家确忘了我也怕黑

You take her home, forgetting that I'm afraid of darkness, too, hints at unspoken emotions within interpersonal interactions. Here it could imply feelings of loneliness and insecurity in a relationship setting where another's needs have been met, but one's own vulnerability (in this case, fear of the dark) has been overlooked or ignored. This can speak volumes about situations that lack empathy in everyday social experiences.
