@HoneyButterPopcorn I get it, I really do. I'm having an unproductive day at home and am ready to throttle someone. I retired from teaching at the end of the summer term, but am meant to be doing a couple of hours of instrumental teaching each week. Well, I would if the bloody school would extract its digit from its orifice and actually put them on the calendar that the kids and I can see. I was meant to be in today, but nothing on the app so I refuse to do a 30+ mile round trip for nothing. I am trying to sort something out for a local group that I volunteer for as the treasurer. One of the others is absolutely lovely and a right laugh; as in lots of such groups there is a degree of bitching and backstabbing, which I cannot be bothered with, so this lady and I moan a LOT to one another.
It is really hard once they start the postgrad work; with undergrads, especially at Oxbridge, the terms are short and they can come home if that works for everyone. Once they are a postgrad, there may be teaching/supervising during the undergrad terms, so their research gets pushed back more into the vacations, meaning you see them a lot less. Now I'm home most of the time, I miss my 2 more than when I was distracted with work. I am hoping to go and visit them, if I can persuade elderly disabled father that he wants to be dragged over there.
So what helps? We have 2 family WhatsApp groups that I know of, one is for the DDs and me, and the other includes DH. I put memes or random funny things on there. If they "heart" or "thumbs up" it, I know they are alive and ok. It's also a good place to discuss arrangements for e.g. Christmas, although for the 3rd year in a row, DD2 won't be home as she has to work. Last week I asked them when they would be free for a call and it was nice to talk to them both. I gave a few options and they chose the one that was best for them.
Once you can rationalise it, remind yourself that you have brought up a successful and kind young man who is making his own way in the world, taking advantage of the amazing opportunities that C has. Feel free to PM me if you want a moan.
