how do you "kick out" another sims

You need to go into household management at the top of manage worlds. Select the household you want. At the bottom of the page there are four options. Click on the two arrows going opposite ways. At the top righthand side there is a little family icon with a plus sign next to it. Click that. Then move across the sims you want to kick out. Then click the check sign at the bottom of the page. You then have a new household of sims you kicked out and you can move them in elsewhere, delete them, etc. Hope that helped!
