When ever you enter into a relationship and you need to store stuff at his/her house, you need to have a back out plan just in case things go bad. This means that you need to be able to gather “your stuff” in a short period of time or risk losing them.
Now, if you don’t care if you ever see these items again, that is fine. But, if you would like them back, you need to grab them NOW! because there is no guarantee that you will ever see them again. Come next week, your valuables could end up in the trash. So, don’t keep anything there that you consider to be really valuable. And if you do, be sure to grab it on the way out.
