I usually try to keep myselfe busy with grooming, cleaning up, running errands, watch netflix. stuff like that. I guess it's normal to be nervous and even rather cute. My bf just straight up told me he's was nervous on our first date and he told me he's still a bit ancious everytime we meet but that it's gone the second we actually see each other. I think that's absolutely adorable! The girl will probably be nervous too, so no harm done.
