1. You don't realize how great USA is until you travel elsewhere, e.g. Europe.
2. Europe will become a mix between the old Europe population and people from Africa based on the faces they saw on the street and the birth rate among different races these days. Soon, white will become minorities there. Yes I know this is politically incorrect by just saying it, but people from different origins are actually quite different, and it takes guts to just state that fact these days.
3. No Air conditioning in many hotels/airbnb and they had to switch places last minute.
The only solution is to have more kids?
