Friends!

When you send free in-game gifts to your friends list for happiness points for your sims, you can send it to the same friend all the time if you want, the game doesn't mind. So, each day, I think its that your sims can send 5 gifts? While the plumbob is on Rufus, or Jenny or Tom, and Rufus or Jenny or Tom will get the happiness points that go towards enough for a Steel Bladder or whatever (that's usually the first thing my sims cash in on). All 5 of those can go to your 3 new friends me1, purple and lorito. Or all to purple, or all to lorito. Every day. There's no need to change it up. Only for your own imagination's variety. The game won't even penalize you if that friend doesn't receive it. You still get the points. Or rather, your sim does.
