So there's cow tipping in the game

Oh, please share more than cryptic one-liners. I haven't seen anything of the sort. Oh, are you talking about the socials that suggest giving certain tips to certain animals? I had one Sim tell a joke to the cow and the cow didn't appreciate it at all. I've shied away from anything but feed, clean and pet as a result. My Sim was so crestfallen I thought she was going to burst into tears.
