Self isolation is very boring so here are some things that will make it not so boring.First of all don't even bother trying online games because your wifi is likely not to be working because of Corona virus nobody will be going into work to work for the wifi companies there for there will be no wifi.
Many people think that there would be nothing to do when your stuck inside with no wifi but there is actually quite a lout of fun things to do like cooking/baking,board games like Monopoly,card games like uno. There many more of things like this to do but you just need to find them in your home or just talking is a good idea like have a nice grown up conversation with your parents.
