Hi
@brayla088,
You can invite other players' Sims to your house if you have them in your Sims' relationship panel. Press on them and you will get the option to 'Socialize'.
If you don't know other players' Sims yet, go to parties or host one yourself. You will be able to meet lots of Sims! You can find information about parties here:
