I agree with Smurf's comment about some people in real life always leaving lights up. I left Muntz and Cletus up because it fits their personality, and Willie's because I think he's too busy working to have time to take them down. I have one random brown house with lights up and one of the blues because even in better neighborhoods there's always ONE person who leaves them up. Probably out of spite.
I really wish in the game we had a way to leave some lights up but have them turned off. That would be perfect. That's just like real life to me.
(Smurf, is that your house with the lights on around the corner from me? The yellow house? Would you mind taking them down? Also, your gate's off the hinge and, no offense, but it looks like h-e-l-l. Would you fix that? Thanks.)
