Underwater Cave:
Hi, and Welcome to my Underwater Cave! I, Alex, will take you on a tour of my water park and be your guide when we enter the dept and darkness of my cave. Please don't stray from the group, you might get lost. And, you never know what's lurking around every corner.
Alex, you make it sound like a spook house.
Well, I had to make the introduction sound good, other wise no one will visit me and go on the tour.
Even I could have made it sound better.
Quiet you.
...
Good. Now put on your scuba gear and enter my cave or just take my tour. Play nicely with the dolphins and keep up and don't fall behind.
