Worrisome future for kids; bad reaction; go-to doctor

I wonder and worry about what kind of world my children will be growing up in  ,... actually, not just my children but everyone's children, and grandchildren as well. I chatted briefly with a friend about this. We're seeing a war of horrible atrocities in Ukraine that threatens to expand, a bitter political divide in the U.S., a virus that hasn't gone away yet, climate issues, and tensions between the U.S. and China. Who knows what's on the horizon. Adding to my gloom is being unable to get my wife a visa and take our two children to the United States. We can't even get a rejection on the waiver for a visa, which God knows we don't want.  A decision may not come for another five months at least. Covid and now refugees from Afghanistan and Ukraine are possibly contributing to the delay in a decision on my wife's waiver. Those folks are obviously in a worse situation than we are, so there's no complaint on our part about refugees being a priority. We just want our children educated in the U.S., especially our daughter, who speaks, reads, and writes splendidly in English, but not so much in Vietnamese; I'm not sure why, but that's the reality. The one school here that conducts classes solely in  English costs about $20,000 USD a year; I'm not sure why, but that's also the reality. My concerns are more selfish than survival, but my children will need every advantage to face and overcome the challenges of a world in flux.

My daughter had a reaction to the chlorine in the swimming pool we go to -- at least I believe it was the chlorine -- with red bumps pretty much all over her body. There was no itching or pain, and the bumps are subsiding. But still. I wasn't affected, but Joanna spent a little more time in the water. Next time, we'll try bathing with a special soap immediately after she's out of the pool. Applying vaseline petroleum jelly beforehand is recommended, but vaseline is difficult to get here. I really want her to play in the pool because it helps a very energetic child burn off energy, and most importantly, she enjoys it. We'll try again once the bumps go away.

The Internet really has become my go-to "doctor" here. I try to use my experience and logic as well, with less success. Dr. Internet (I call her Dr. I for short) believes the nasty pain on the outside of  my left foot near my little toe is a tailor's bunion. It comes from walking way too much in inappropriate shoes, and genetics. My Ukrainian mom had foot issues. Anyway, Dr. I recommends 10 minutes of ice application to my sore foot three times a day and she also says to take anti-inflammatories and get more comfortable shoes. Being a good patient, I've been icing and drugging, and my shoes hopefully will arrive in a week or two. I can walk with a little less pain now, so I think Dr. I is on to something.

Delivery service here is very iffy for items coming from out of the country. Services like DHL and FedEx now want passport number, bank account statements and proof of purchase to get items out of Vietnamese customs. The eight books I ordered for my kids arrived this week; bunion-friendly shoes should be coming in the next couple of weeks. I ordered four books three months ago that never came -- lost $85 on that deal. I don't care about the money because I really wanted the kids to get those books. .... My Kindle streak is at 851 days in a row. Alexander Hamilton has reeled me in. .... My son Elijah loves all music. His favorite is Vivaldi's Spring. Excellent taste. He loves dancing, too, but to his credit he doesn't dance to Vivaldi; he just listens.
