On thursday I sent out several (5+) private messages on facebook to people I was thinking of, and hadn't spoken to in a while. FB tells me that they viewed the messages, yet not a single one has replied, commented, or otherwise acknowledged they received the messages.
Is there any way to bring this up beyond a passive agressive "Gee does nobody know how to respond to a private message anymore?" status post? I am more annoyed than hurt, but I'd like to make it known somehow that it isn't ok with me.
