"You're a bit of an airhead aren't you?" She says looking at you like you're stupid "I can't keep explaining it to you i have to go soon. This isn't my only job you know.

To do this i'll grant you something of the following so choose wisely" She waves her hand and a few items appear in front of you. Which do you choose?
