I can see what you're saying, for sure. I had a cousin who used to post interesting things about politics (not preachy or rambly, just relevant), food, travel, wine, the world. Then she had a baby and when the Boston bombing happened, she posted a photo of her sleeping baby and said "I hope this photo of peace reaches those in Boston and reminds them of the good in the world." and a video of her other kid dancing that said "let this video make your day!"

::record scratch:: WHAT?! What happened?! Your world used to be so big, and now you don't interact with anyone unless you can relate it back to your kids, usually with an out-of-place winky face. And I know she's online because I see her all the time talking about mommy-things. So, like OP, no word of congrats when I got a master's even though she has 2, so knows what a big deal it is. My Mom tells me that I'm reading too far into it and stuff, but... I disagree. For those of us that are intertwined with social media, I do think that a person's online presence is quite telling. Surely, she saw ONE of my posts about my thesis/ master's, and... nothing. I won't unfriend her, but I've stopped liking all of her constant "mother's love" and "being a mommy is the hardest job ever!" posts because a 1-way friendship is not worth it to me.
