such is the curse of being Pantsu
in all seriousness, out of all the Spanish speaking nationalities that I've met, the Colombians have generally been the nicest ones, and their accent/speech manners are also the nicest, and don't sound as if they'd only completed second grade or were raised by an alcoholic goat.
Mexico has many accents, almost one per state, but roughly divided by region, the north (my area) is loud and rough, people often think we're pissed off or being confrontational, when we're probably just happy or just having a normal conversation. Central Mexico sounds goofy in the way the words are enunciated, can't really explain it but is unmistakable, you hear it and know they're from Mexico City or near it. Southern Mexico sounds lazy, almost as if they can't finish the words, and sounds nasal for some reason.
Spaniards rarely sound educated for some reason, the accent is fine but the way they speak the language makes me cringe.
