How Long Should The Christmas Decorations Stay Up?

I don't know about you, but the holiday season goes by so fast, I don't have a minute to stop and enjoy all those decorations we spent so long putting up. I know many of you have taken them down already, but I just can't bring myself to do it. Now that I have a little time, I want to enjoy them. But how long is too long?

Parentdish says you should start taking them down right after New Year's Day, but that's too early for me. Frankly, I want to leave the inside decorations up until the end of this month. What do you think?
