I have been having this question in my mind for a long time now.From the time I moved to the U.S(about 2 yrs back) till about 6 months back,I did not feel it too much since my interaction with the outside world was very limited. But for the past 6 mnths,my son is going to school.I usually drop and pick him up from school.Most of the other children in his school are either American,African-American or Mexican.I get to see a lot of the American parents during this time who also come to drop/pickup their kids. I feel they just look through me like as though I am invisible or they don't look at all.Even if I try to look at them to say a 'Hi',how can I even try when they don't look at me. They deliberately try and avoid any interaction with me. Among themselves they get along very well eventhough they have all met each other at the same school only and that too,they have known each other for a few months only.Is this because I am an Indian? My intention is not to build a life-long friendship with any one of them,but to just get to know a few of the parents who send their kids to my son's school,so that while I wait to pickup my kid,I can atleast chat with someone.I feel so looked down upon sometimes. Do any of you here in the U.S feel the same way ?
