When to say nice to meet you?

Answer 1

When you meet someone for the first time, it’s common to say "Nice to meet you." Whether you’re at a professional event, like meeting a new colleague or client, or in a social setting, this phrase helps set a friendly and positive tone. It’s also perfectly appropriate to use in virtual meetings when you’re introduced to someone new. It’s a simple way to show that you’re pleased to make their acquaintance and that you’re looking forward to the interaction.

Answer 2

When you meet someone for the first time while shaking their hand. Or when you're saying goodbye to the newly-met person.
