Re: eh?
It's more like this: whilst you're out, some advertising company decides, without telling you, to 'add value' to your house by painting an advert all across the front wall because they're sure that:
- You'd be interested in whatever tat they're trying to flog and will thank them for educating you.
- The best way to get the message across to you without irritating or upsetting you in any way at all is by spoiling your house.
After all the company hasn't charged you for defacing your house, therefore it must be good for you. I can't see how anyone could be upset by this.
