Spring, and especially summer, are tourist seasons, at least here. And unfortunately, most tourists are bad tourists. It's easy to distinguish who's who: the good tourists, and the residents, are the ones looking embarassed, while the bad tourists are the ones embarassing themselves.

I have here attempted a simple categorization of tourists. It's doubtlessly incomplete, but it's a start.

Homo rassegnatus
The Good Tourist, or the Resident. Either way, somebody who has to bear Bad Tourists.

Homo depressus
Tourist guides, teachers, anybody who loves a place and attempts to explain its history to others, only to have them being distracted... and having to repeat the same exact thing to different masses of bored people every day.

Homo ricordinus
You've seen them. The ones who insist on buying a souvenir (or two, or three...) everywhere they go, so, by the end of the day, they look like a walking souvenir booth. They spend lots of money on souvenirs, and at the end of the holiday they do not even remember what they visited.

Homo doloredipedibus
Usually female, but there are a few males. Members of this subspecies insist on wearing the worst possible choice of shoes for walking around a city. You often hear them loudly proclaming how much their feet hurt, or walking like they're walking on hot coals, with their shoes in hand, or even sitting on the edge of a fountain with their feet in the water.

Homo photographicus
This one's gotta photograph (or film, alternatively) everything. Seeing everything through a viewfinder, always in search of the "perfect photo", risks running headlong into lampposts and road signs. Never really remembers what was visited, only taking lots of good photos.

Homo gregarius
You will never see one of these alone. They always go around in herds, those same tourist herds that tend to stop traffic and unnerve tourist guides. They are always crowding around somebody - a guide, for instance, or even one of them who is reading out loud from a guidebook - or something - a statue, a painting, a fountain, you name it.

Homo solitarius
The opposite of the previous kind. Wouldn't be caught dead with another tourist. Has been known to try to visit museums at night to avoid the crowd and the guides.

Homo inmediusviae
Usually male, this tourist stops traffic. It doesn't matter what he's doing in the middle of that road - he could be taking a photo, he could be one of three dozen homo gregarius crossing the road in single file, he could be tying his shoelaces, he could be consulting a map... he still stops traffic.

Homo perdutus
This tourist gets lost, even with a map. If female, she will be asking for directions to a place or monument standing right in front of it. If male, he will be hopelessly lost and adamantly refuse to ask for directions.

Any additions? :)
