There are subjects that I wouldn't mind discussing with my spouse that I wouldn't discuss with any ten year old.
There are discussions that I would not mind having with relatives that I would not want to discuss with a ten year old in the room who is NOT going to have similar issues with the family medical history due to gender. At least not while they are still ten years old...maybe when they get older, they will need to know that THEIR children or grandchildren could be at risk for _______.
I have hearing issues (worked on the flight line at a military base AND I am easily distracted - no formal diagnosis, but they didn't HAVE testing for the issue in the 1960s and early 1970s for kids my age in small rural schools). I've learned coping mechanisms over the decades - but they involve wanting to minimize human voices in the area (instrumental music is less distracting than singing, singing is less distracting than "talking" in any form - radio, tv, movie, or class presentation). A noisy computer, depending on what is going on, can be more of a distraction than I can easily & comfortably cope with. A tv show or movie is even worse....
I can understand being unable to relax and enjoy a conversation because the surroundings are just too distracting...whether it's being crowded, the feel & smell of "unclean" upholstery (or at least it is coming across to MY senses that way), and a computer being used by someone else...would make it very hard to deal with a conversation - whether I was visiting one-on-one with a relative or part of a small group.
I find that counted cross stitch helps...especially with introverted relatives who need to "drop out" when they reach a point where they can no longer deal with other people for a while. Sitting in the room together, while both of us plied our needles on "complicated bits" allowed the introvert to recharge - maybe more slowly than she would have if she had been alone - but with an extended family sharing one house situation - there were very few places to be alone...laundry rooms don't tend to have seating. A great room (living room, kitchen, entry, and breakfast nook in one open area) did not allow enough separation for being alone, either....
But something to fidget with, even if it is NOT a laptop, tablet, or desktop computer might be something for the OP to consider. Knitting, needlepoint, counted cross stitch, crochet, or some kind of finger weaving (if she's into costuming, it makes great trim or belts) is easy enough to carry around (tote bag), engrossing enough to prevent boredom, and there is the "I need to finish this for a present, get a costume ready for the next convention/faire, or whatever" excuse or even "just to see how it turns out, as it is an experiment"*!
*I make my experiments in red, purple, or a combination - even if they don't work for my own use - they get donated to my Red Hat Society group for use as door prizes, taken as White Elephant gifts, or I teach a crafts class (only handwork can be done - no loaner sewing machines available in the classroom that we use).
