Lack of Consideration for Others

[blessed]

Teens seem to be so wrapped up in theirselves - they simply have little consideration for others in the home. Our son brought home a guy we've never met at 9:00 pm tonight. They've all been told they need to give us a little notice if they're bringing someone home - especially at 9:00 pm. I've worked all week, ran errands tonight and am very tired. I was just getting ready to put my PJ's on when the front door opens! No warning whatsoever (isn't that why we gave them cell phones?). He leaves his things all over the house, does little to help out and when we confront him about it we just get attitude. Anyone else dealing with this problem? Got ideas? Please share!
