Agree to help her at the college

You tell her you don't have anything better to do, so you might as well. She seems happy at your reply. "Cool! If that's the case, we should get going soon, I promised my professor I'd be back sometime today, while the sun is still out. The infected seem to love going out at night, so the gate won't be opened, even for a minute."
She gathers her stuff (after you both get dressed first of course, if applicable), and before you know it, your out the door and on your way to college. Susanne seem to know every inch of the area, all the shortcuts, and where the infected like to gather, and it doesn't take too long at all, about twenty minutes or so.

The college consists of a couple buildings and a field, a tall cement wall surrounding the buildings perimeter. The field is surrounded with chain link fences, crudely patched up with metal sheets and barbed wire. The entrance to the compund is a electric car gate, with a hodgepodge of metal plates and signs attached to the front. The guardhouse windows has been boarded up. And just your luck, there's a small gathering of infected at the door, most of them are banging on the metal plates, but a pair is banging in a diffrent sense. From your count there's about seven or so of them.

"Too many, they won't let us in that way. C'mon, I know a secret entrance." She waves at you to follow her, and she dissapears into a house neighbouring the wall across the street.
