This may not seem like a big deal to you, but it is to me. I am a greeter by nature; I feel it is important to acknowledge someone's presence with a hello, hey there, good morning. This is especially true in the library setting, where I want everyone who enters to feel welcome. But many students I've come in contact with over the past few years not only will not initiate a greeting or conversation--they won't even reply to a hello. I've even encountered adults who will pass me in the hall, or enter the library, without a greeting or nod. Whether it's social ineptitude, social exclusion, introversion, or full attention to another matter, I'm not sure.
I am sure that the pleasantries exchanged today at my circulation desk were warm and heart-filling for all involved. I hope those two young gentlemen continue their habits of friendly communication, and influence others to do the same.
