To Paint or Not To Paint That Is The Question...

We've lived here for almost 2 years now..and I don't think the place was newly painted when we moved in. I'm starting, no I am, getting really sick of the same color walls in every room! So I've found some paint that I really like...on Craigslist of course..someone bought too much and is selling what they don't need really cheap! It's a color that I had considered for either our bedroom or the kitchen. Does that sound a little weird liking the same color for either the bedroom or kitchen? However, since we're only renting here is it worth the bother? Now I have wallpapered before in homes that we rented but we were renting with the intention of living there for quite a while. I have NO intention of being in this home for any long period of time..2 years is a while though isn't it?? Guess I should have painted 2 years ago! I can't get over to pick the paint up until Tuesday anyway...so I think I'll hold off on it and IF the person still has it on Tuesday afternoon that will be my 'sign' that I'm suppose to paint!
