Cultural Tip
While 'De rien' is perfectly acceptable in most casual contexts, French speakers often switch to more formal expressions like 'Je vous en prie' when speaking to strangers, elders, or in business emails. Also, avoid using it after a very big favor; a more appreciative response such as 'C’est avec plaisir' shows greater gratitude.
