Are dictionaries addictive?

It's official, dictionaries are now an obsession for my son. He has been slowly collecting them over the past couple of years. This morning he pointed to all the dictionaries in his book collection and made a pile. I put them beside his new glider rocker and he is now flipping furiously through them one by one. As you can see in the second picture the older ones are missing covers or falling apart slowly. Time to start looking for more dictionaries. At least I have one more idea for gifts for his birthday!
