Hi,
1.'In/At the beginning of the month/book/movie.'
Are 'in' and 'at' both fine to use here? If so, what is the difference between 'in' and 'at' here?
2.'I thought he loved me; perhaps he did in/at the beginning.'
Could we use 'at' instead of 'in' here? What is the difference between 'in the beginning' and 'at the beginning' here?
Thank you very much.
