Indeed looks like actually typed with a typewriter, not a font.
But if you want to find a similar looking font you can give it a try here: http://www.dafont.com/theme.php?cat=113&text=the+perks+of+bein+g+a+wallflower&fpp=500&psize=s

It looks very close to a mixture of Trixie Rough Light and Trixie Rough Heavy

It looks kind-of like this, but with some editing done to it.
