<human>: My girlfriend is, hands down, the smartest person I know. She is almost finished her doctorate, yet still Facebooks like a teenager, tagging me in all of it. I am tagged in every movie or show we watch, every restaurant we visit, and every meme she laughs at. Any just-out-of-the-ordinary experience is chronicled and posted immediately. Here's my facebook feed for the last 24 hours - tagged in two memes (one I don't get at all), tagged in the show we watched last night, and tagged in a picture of our dinner. It might seem petty, but after five years, it is has become rather grating every time I see a notification pop up. She is *that* person on facebook. It never stops. My reaction to a facebook notification has changed from *aww she's thinking about me* to *what meme from a show I don't watch did I get tagged in now?* I don't want her to feel unappreciated or think that I don't want her attention. How do I approach this topic? Is it worth discussing, or am I being ridiculous?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Brilliant, soon-to-be-doctor girlfriend facebooks like a 13 year old girl. How do I approach this? Should I approach it at all?
