Dear Friends,

Last week, I read in a book..."I have enjoyed talking with you"

However a friend of mine told me sometime that we use "talking to" instead of "talking with".

Shouldn't it be like "I have enjoyed talking to you" ?

Eagerly looking forward to your kind assistance.

Both prepositions are used and correct. To may sound more idiomatic to many natives' ears.

Some might say:

You can mostly use them interchangably but maybe "with" is a bit more equal whereas "to" is more one way. If you talk to someone then you do more talking and they do more listening but if you talk with someone both talk and both listen.
