Most of the time complete strangers send me Friend Requests. We have no Mutual Friends in common and we are very clearly from different backgrounds. If their Walls have open histories and their accounts are replete with posts and photos no matter how inane, I take them in.

I admire users of social media who are not ashamed of everything they are and step up to without the slightest pretension and disguise. As a matter of fact those are the very people who end up being my long-time students.
