Jenn, for example (hope you don't mind me using you as an example, Jenn), posted that she was going to be away a lot and not around so much when she got pregnant and has had so much going on in her life, how to get ahold of her, etc. I did not for a second think that she wanted extra attention (though don't all new/expecting moms deserve some!), just letting everyone know the reason for her being not around as much if at all and that she was truly just busy doing other things.
I myself recently took a break from the forum for a few days, thinking it might be longer, but I had a few people that I was in PM contact with, and figured they might not know where I'd gone if I just up and left. I wasn't looking for attention, rather I was sort of hoping not to be noticed more than anything else. I was glad the post was removed, in hindsight, and I didn't stay away as long as I thought I would, anyway.
Most of the time, if one is going to be away because they are upset, it's best just to go quietly, and figure things out for yourself.
