I still remember when I was 6 years old,  one day I walking on the street and I saw my aunty I called her name but she did not answer me and I just called her again and again, however she just keep walkingme and ignore me.
  That makes me little bit sad, so I ran to her and hugged her said :"why u don't answer me and ignore me, I miss u so much." and then I look up found this lady are not my aunty!!! On that moment I want dig a hole and drilling in, cause is so so awkward, I almost cry on that time.
