Height of absent mindedness!

Yesterday, a friend of mine said he'll come to my house to meet me. He showed up a bit late but nevertheless he showed up. We talked about various topics for quite a while. Now let me tell you about one exclusive trait that my friend has. He has problems remembering things and stuff. His trademark absent mindedness came to light when he got a call from his dad. My friend had left his house door open when coming over to my place. LOL! Later I got to know that nothing was stolen and everything was safe. A very lucky guy indeed.
