No doubt you have liberty to do whatever you want and to live a lifestyle of your choice.
However the traditions and culture is different in India.
It is not compulsion on you to follow the culture and traditions that are imposed by your in laws.
They may be orthodox and would like to maintain their family respect and reputation hence such restrictions may have been imposed against you.
These are petty issues and no where they are going to curtail your liberty.
This mentality can be overcome on the passage of time.
Your marriage is hardly one month old hence at this stage it is very important that you maintain little flexibility.
Your wrath or anger over their instructions may lead to a disaster in your married life, especially if your husband is out of the country, he may not know the real facts, therefore you should handle patience, maintain a low profile at home, adjust yourself and live a life of harmony. It will help you to avoid misunderstandings and conflicts.
Your initial agitation may lay a foundation to an unstable married life for ever, hence think about all the pros and cons properly and take wise decision
