Stop in for a cup of coffee

Nieghbor's real nice guy and is building a little deck in the front yard. He's mitering the floor with the front face. It's going to open up in a year and prob look like h*ll in 2 or 3. But there's no point in saying anything. He'll find out soon enough and if I tell him now its not going to change anything but maybe come off as a smarty pants.
You smarty pants! I love suggestions from people that know.
