Let your father do as he likes. He needs time for himself and is an adult. He took care of your mother and knows what to do what is best for him. Traveling is no good idea. The thing about this virus is if it comes to it they do not know how it develops, what it infects, how it works if it will ever leave the body, if and how fast it mutates. It spreads fast let's hope in 8 weeks time we have had the worst behind us but I am afraid this is a thing that will take months. 💕
