I see. Thanks. Just wanted to know if there's a way to say those two in a single sentence I love wordreference!If you know this person it would be kind of strange to use this structure, though.
Is it someone you know? You wouldn't really mention if it is their second time if you do.
The usual way to greet someone would just be "Welcome" but if you /need/ to say it, Owlman's way would be perfect!
