Zach arrives at an animal sanctuary run by David.  | 
 | Good morning.  Are you Zach?  | 
 | That's right. You must be David. Pleased to meet you.  My professor said you needed some volunteers to help clean up the sanctuary?  | 
 | Yeah, we're having our annual cleaning campaign.  | 
 |  | 
 | That's great! Thanks for being here. Please just fill out your details on this registration form.  | 
Zach fills out the form.  | 
 | There you go. So, what's next?  | 
 | Could you please put on these gloves and take this garbage bag?  | 
 | Okay. Do I need any training?  | 
 | Don't worry, it's simple. Just pick up any litter you find, and don't make eye contact with the gorillas.  | 
 | What happens if I make eye contact with a gorilla?  | 
David suddenly looks serious.  | 
 | Then I'll have to find a new volunteer. Shall we go now?  | 
 | Okay. At least I'm getting extra credits in biology...  |
