Instead , I admire the girl in the mirror , grinning back at me , her acceptance letter clutched to her chest . Her empathy is purely amazing . I want to kiss her in celebration , but I can not express any love towards my Ego in public . Instead , I fix her hair , and we stand up in unison , and leave the cafe .

Question: Why is the narrator trying to suppress their affection for the girl ?
Answer: They are in a crowded subway car .They are in a quiet place .They do not want to show their true feelings publicly .They are in an area restricting noise .
