If they're friends, they have contact info for everyone, right? They could schedule some kind of gathering when this is over to the extent that it's allowable.
WRT being robbed of her last semester, it sucks, but think about people who have lived in war zones and didn't get to have their schooling, at all, lost most of their friends and it lasted years, rather than months.
Like I said, she gets it! She understands the need for the situation to be managed the way it is.
Certainly she and her closer friends will maintain contact through this and being in a Sorority, they will probably have some type of post-CV event, but she is a very relationship oriented girl and not having the chance to say goodbye to the special needs kids she has bonded with, casual classmate acquaintances, her favorite teachers, etc. is a disappointment - maybe I should phrase it as "a loss of opportunity for closure". She doesn't whine about it, but she is honest with herself about it. She is very aware that her disappointment is far below the crisis that many of her peers (and others) are confronted with. She commented on how fortunate she was that she had not yet signed a lease for the apartment she planned to split with a friend, so while she will miss the May employment she had expected, she is lucky not to have such obligations/bills to pay - she can simply move back in with me for the interim without any financial entanglements!
I know a lot of people complain about the current generation of youth being spoiled. I have to confess that I have generally made life easy for her, I always felt like a kid should be working part time before they start high school (I had a paper route starting 7th grade and worked throughout my school years)! However, she started helping teachers with special needs kids in Elementary school and has found a way to commit time to helping these kids ever since. That combined with the time demands of being on her school teams for debate, basketball, track, and cross-country caused me to back off of having her maintain a job (she got her first job the Summer after HS graduation working for Marco's Pizza).
Sorry for the ramble, but I have been blessed to have a child who is a wonderful example of humanity! Obviously, there are plenty of kids out there who only live to play x-box, I always wonder what percent of these will be able to properly adapt to the needs of being an adult (especially given the abnormal demands of global warming knocking at the door)! I know I am biased, but my daughter and her closest friends lead me to have some optimism about the future, which is a good thing as we are sheltering in place!
But to your post, I get where you are coming from, for me, ending school contacts a semester early without warning would not be a big deal. My daughter (and, I think, more often girls) is just very people/socially oriented. The CV shelter in place is so much easier now than it would have been 50 years ago - back when you paid like $1/minute for a LD phone call and there was no internet or cable. Domestic disputes would probably be through the roof (they probably are higher than normal as is). We are physically isolated, but far from mentally isolated!
