Argentine Postal System, the Sequel

I had vague recollections that I didn't exactly Bond with the postal system last time I was here... had forgotten the sheer torture one has to go through in order to send a parcel. Okay, first let me deal with Box. Box and I took a cab miles away and finally located the entrance to the post office. One guy inside measured Box - exciting, intimate moment there, Box is getting more action than I am - and established that he (definitely male, as just damn stubborn and kind of annoying) was too large to post. The string of expletives that issued from me at that point essentially convinced the guy that he really should just ignore the rules on this occasion or him and Box were going to become somewhat more intimate than either of them had ever planned, and I proceeded to the counter for weighing etc. All going hunky dory until it came to paying, and for some obscure, unknown reason the Argentine Postal System doesnt accept Visa card. After establishing my horror at this revelation, I set off in pursuit of a cash point... which I eventually found. Anyhow, yes, I did send Box. Hopefully we'll meet again, some sunny day. Or rainy, not fussed.
Then today... well yes, another of those 'I should have stayed in bed' days. Set off to post small package, post office round the corner was closed due to power failure so had to walk a ridiculous distance to the next, where I was informed my parcel was not wrapped correctly for postage. Asked the lady how she expected me to wrap it, if not in brown paper with tape, and apparently - APPARENTLY - they want me to glue the paper down. Who in their right mind is going to send a parcel half way round the world that is merely glued together?? Especially one which contains a damn ball-gown?? This means I will now be carrying around in my rucsac, along with a laptop, selection of feminist books, series of Jeeves and Wooster DVDs and the other usual travelling gear, a ballgown.
Have retired to my room for the rest of the day, primarily to download as much as possible because I don't know when I'll next be able to use my laptop on the internet. Would be armed with selection of empanadas (essentially miniature pasties, to enlighten the Brits reading this) but the bakery had no vegetarian ones today. Not one. See? Just not my day.
And this is the last post on here for a week - I'm heading into the Amazon. Replacing really rather luxury hostel room with a hammock. Praying for no close encounters with either crocodiles, snakes, piranhas, bird-eating spiders, jaguars... the list is endless. Just wish me luck. And never, never come to Argentina with a view to posting anything. Words of wisdom for the day from Jane.
