Which social interactions do you think TS4 is missing?

Npc sims should be able to ask to be boyfriend/girlfriend or propose. This can possibly backfire game play wise if it is not done properly. So when this happens there should be some prompts of yes, no and let's just be friends. Or for those who can't decide and want to leave it up to chance let there be a fourth option to randomize the three other options.

Begging and Offering. Sims could beg sims they know or don't know for something usually dependent on their needs or traits. Say if Bob gets turned down for a proposal, he could resort to begging. Sims visiting your home can opt to beg for food if they get really hungry. Offering would be different than give gift in that the receiver can choose to accept and use what was given. Like a drink would not go into their inventory, it would be consumed. Offering would depend on what's in ones inventory or what the receiver needs or desires as well as the traits of the one offering. A flirty Sim could kindly offer a kiss without the negative romance when turned down by just trying to kiss. A cleanly Sim could offer to clean a mess as slobby Sim can beg for help cleaning their mess.

I want soooo many interactions, they all just left my mind right now. But one I can think of, I want other sims to tell me why they're in a negative mood. You can try to calm them down or discuss their mood (if you have Parenthood) but they don't tell you what's up, like with dogs. If an NPC is starving, I'd like to be able to know and, idk, feed them.

Oh, just thought of another one. I want bickering. For siblings and marriages (especially old ones). Maybe it could just come up depending on their mood or their personality (if they had any), but yeah, bickering in the way you only do with someone you're very close with. And it wouldn't negatively affect their relationship like arguing.

Another social I would like to see as an option for the player is when directing a pregnant sim in conversation with another sim there would be the option to: "Claim (sim name) is a parent to the child" or "Ask (sim name) to be a parent to the child".

This would work regardless if the pregnancy is from wohoo, alien abductions or some other way. The pregnant sim should also be able to use it on as many sims as the player want and they would not need to have a romantic relationship with each other. The speech bubble could be the baby symbol and then the symbol for alien (or the symbol for alien abduction if there exist a symbol for that).

I do like the "Adopt as caregiver/care dependent" that already exist in game. And I guess the biggest difference would be that the other sim would care for the child/children already from the start and be considered a parent in the relationship menu instead of caregiver, but more importantly is that they would not be able to start a romantic relationship as the child/children age up to adults. After all it is their child/children.
