@HelenaKB99, which format are you playing on, a console or a PC/Mac? Also, do you have any extra packs (be they Expansion Packs (EPs), Game Packs (GPs), or Stuff Packs (Sps)?) 🤔 The more packs you have the more options you will have, especially with EPs and GPs because they affect gameplay more than SPs do.
That said, even without any additional packs there should be some more options. Depending on your Sims's personality traits, there should be a few options based on that. For example, if your Sim loves the outdoors, there is normally an option for your to "Enthuse about the Outdoors" , and Family Oriented Sims should have the "Boast about Family) option.
Also, not all options are available every time…. sometimes with Genius Sims, there will be an option to Discuss Ideas, and other time there will be an option to "Showoff Invention".
Other interactions that should be available regardless of personality traits or packs you have installed are
Discuss Interests, Talk about neighborhood changes, Flirt, Ask if Single, Do Impersonation, Tell Goofy Story, Tell Dramatic Story, Ask About Local Fishing Spots, etc. 🙂
Since you are new to the Sims you probably don't use any Mods or Custom Content (CC), but if you have any of these that are outdated, this could also cause problems in your game. 🤨😞
Please update us of your situation! 😇
