I am looking for some kind way of replying to an email when the other person is saying that he will be traveling and asks for more time to complete something.
It appears that "Have a nice day" could have some negative connotations (https://english.stackexchange.com/questions/57692/what-s-wrong-with-saying-have-a-nice-day), so I am wondering whether saying "Have a nice travel" is a good idea?
