why don't they answer my facebook messages?

[Yolo]

Every since i moved to Brooklyn, this summer i been trying to catch up with some of my old friends i have not seen for a long time 3-5 years from Manhattan and we had been very good friends, i found them on fb and some of them respond and wanted to catch up while some of my other old friends even recently from middle school (im in high school now) just ignore my message and not bother taking 5 sec to answer the question. Why are some of my friends so rude when we were good friends in the past......

Well There Friends From the Past So its Possible they Could've Changed Since you last Saw them if There Not Answering your Messages Either they Forgotten About you Or They Haveint Been On Facebook or They Read the Message and Didint have Time to Write Back Try A Wall Post and See If That Gets There Attention Good Luck

you had been very good friends, they could not see those messages. Wait for a period of time, and give them time to time for yourself.
Good luck for you!
