Be nice.

You go and trade in the clothes for stuff that fits. You decide against bras, you have heard they are bad for you anyway and you can just wear tight tops instead if you want some support. You also like the shorter skirts, they feel good on your legs. At the store you decide that since you don't really have or need to get a job right away you can do some cooking so in addition to the toiletries you need you get some food that you can cook for the two of you.
