Another one bites the dust

One of the girls in my office just got engaged. Yay for her! I am happy that everyone is trying to get to their happily ever after but at the same time its like "great, another person that I will hardly see and will have baby on the brain next".

I know I shouldn't sound so negative and I am truly happy for her, it's just strange. I have been off-kilter in my mood lately.
