Credits: Original Mod created by yakfarm on Mod the Sims, which I am updating for a long time already and now uploading here as well.

Original Text by yakfarm:

Stops Sims from standing up to greet.
When seated, Sims will only greet each other by waving.
They will still greet each other normally (i.e. hug) when both of the interacting Sims are standing.

Optional Addon:

Cats & Dogs - Which adds a testset to the PetToSim_Initiate Interactions. This should stop Pets from forcing Sims to stand up to lick their face etc. as well.
