Why is the welcome wagon so creepy!

The stupid thing is, if my sim did that at another lot when visiting they'd probably ask her to leave. The fruit cake was in the flipping fridge! I didn't think to ask them to leave separately, thankfully it's timed out now and they've left, not until they ate all her leftovers and left plates of half eaten blackened bass everywhere though.

edit - on the plus side Brandi's eldest, Dustin, visited and fixed the sink whilst he was over!
