Business Card Storage: I have the technology.
The presentation of business cards is also important. They must be admired and looked at thoroughly before being put away. They must be handled by the edges, and the front (as Brian Clegg has pointed out) must face the receiver, and when the receiver finally does put them away they must go into a special wallet. Luckily Hodmandod Senior already has one of these special wallets, and has just gone through it taking all his old cards out so mine might go in. This has caused him to spend some time reflecting on the good 'ol days, when the place he worked for had a library and he could look stuff up in journals, and there were people around him occupied in similar cerebral activities, and he would make discoveries... and life was good.
Poor Hodmandod Senior - all that has changed now. One by one all the research scientists have left; and where there were once hundreds there will very soon be just Hodmandod Senior alone.
