It takes someone visiting to put a picture up?

We are so excited that my parents are coming to see us in Jersey! About a week ago Zach said "We need to get pictures on the wall!" The reason we haven't is we have been trying to decide whether or not to paint and we know this house is temporary (yes 2 years is temproary for me!) so I really don't know if I want to spend a lot of time decorating. And we haven't had family pictures in a long time so I really want to get new ones so they can be put on the walls. Then I realized his real motivation.....my parents visit! Honestly they don't care if there are pictures on the wall, but for some reason it bugs Zach. He also got his peg board made for the garage so my dad would see how organized he was! Again my dad loves tools, and stuff, but does he care......no. So I guess I need lots of visitors so Zach will get all the projects done!
