I am fascinated by how many people do not know their neighbors. When I was a kid all the people on the block knew each other. All the children knew that everyone was watching them (and would report back undesirable activities to mom and dad).
Today the connectivity amongst people on the block is not as strong. Sure, there might be some people you know, and the courtesy wave is popular when folks walk by... but many people don't know that much about those who live close to them.
It is worse at work. Do you know the people on your block? In your building? In your elevator bank? How about on your floor?.
There is no excuse not to know the people who work on your floor. If your work for a company that is not so large as to occupy the whole floor... and you don't know the workers in the business next door -- then shame on you. This gets you an "F" in Networking 101.
But you can bring your grade up. With the holidays coming... make this the point that you meet the neighbors. Invite the other companies on your floor to your office for lunch. No agenda, just people meeting people. Cater in sandwiches and have everyone go around the table and explain who they are and what is their role at the company.
Maybe they will become a great referral source. Maybe not. Either way, next time you are waiting for the elevator you will be able to talk to each other instead of staring at your shoes. Making friends is always a good thing.
Same idea for those who live on your block or in your apartment building.
Have A Great Day
