I was close to a colleague and yet when I left, it didnt end up being the case that we really stayed in touch. She tried but I was going through a lot what with a new job and then a significant birthday (mine and several others in my family ). It's been seven months now and I do still think of her from time to time but of course, life gets very busy and she's not on Facebook which doesn't help matters as it's much easier to stay in touch with peoples lives that way.
Anyway. I heard from other colleagues at my old place that she has had some bad news about her health. Do I contact her again or is it too late for it to be welcomed? She was very good to me when we were at work.
