Type. 

In this lecture we were looking at how you can create a layout from a technique known as 'painting' this is where you paint the mood using blocks to express the feel of the subject your looking to portray, then this is gives you a layout. 

For example the friendly layout has a big margin and a lot of white space around the squares yet the squares where the type would be placed is close together creating a sort of bond.  

Angry..

This is too thought about. If you are angry, your irrational, mixed emotions, so you wouldn't have even square it would be all over the place.

Friendly..

Friendly is happy, happy is not so much a light font because it is not quiet! its quite a bold, strong, level feeling. And if you were to express happy/friendly sing type you wouldn't really use an extra light type. 

Precious..

Precious you want to express a unique feeling, slightly expensive maybe. A bigger bolder shape against a lighter smaller shape would probably work better.
