Question

is my teacher is a prison guard when it comes to giving passes, an analogy, metaphor, or similie?

Answer 1

not a simile because they use like or as. Could be an analogy but I don't think so. I think its a metaphor because they do the same as similes just without using like or as

Answer 2

It cant be a simile because a simile uses "as". 

It cant be an analogy because an analogy describes something in more than 1 feature. 

So I think it is a metaphor because a metaphor describes something so you can imagine it or there is something you can relate to.  

Hope this helps
