From a trip like this for Peru:
Insect bites will not go away
You will look at stairs in the subway with no angst
You can actually read signs in Spanish
Beds are such a pleasure rather than a given
Same with toilets, Western that is
Hiking locally has some appeal
Until you realize that you really would rather not hike
And that you will be asked for your advice multiple times for the next several decades
or you can write about it somewhere and we can be directed to that page, so as not to ask for advice when the time comes ;)
