I don't get it

I am in grad. school, my friend who is also in grad. school at the University of Notredame wants to open a bakery, now this doesn't sound so crazy right. I mean for all you know he is a culinary major or hotel administration major but NOOOOOOOOOO my friend J is working on his Masters in Computer Science, so yeah I don't understand how a bakery and hard drives coexist in his brain but they do, it is like mii researching wine clubs for a winery that i want to buy after i graduate.
