My mother was also widowed (in the 70s) before she completed 50 and some of the people in our community including close relatives asked her to visit their house within the 10(?) day period (I don't remember the exact number) as she would otherwise have to avoid their houses for a whole year. There were many others (also from our community including close relatives) who said that they were not asking her to visit their house within the statutory period as she was free to visit them any time she wanted and that she was always welcome in their homes. My mother did not visit any of the houses of the people who spoke about visiting them during this statutory period and in fact we (father's immediate family) hardly ever called on them after that and our relations with them were extremely formal but polite.In my own case, my mother is a doctor and from the beginning she mocked and had mostly contempt for Tamil Brahmin society and culture. Not without good reasons, because her mother (my grandmother) was a widow and in the 50s and 60s in India tamil brahmin widows were treated very poorly. So it is no wonder that my mother grew to have an inherent dislike of our culture.
My mother's experience was first hand but did she have to hate our (Iyer) community for the people who felt that as a widow she had lost her social status OR think of many others (also belonging to our community) who invited her to social functions including weddings (during this period) and asked the couple to do namaskaram and take her blessings. My mother is no more but she did not hate the community or the culture because culture is what the people practise.
And also, while the parents (mother in particular) are a very great influence on a growing child, it is important later when they grow up, for every mature person to ask himself/ herself whether everything imbibed from the parents is desirable.
