I shall post you a box of things from my university room in the UK. It will be shoe/beer box sized with various random items that I/my flatmates have amassed whilst here.
Note: contents may be a bit strange.
I am intrigued. Note: contents may be a bit strange.
* I would need some more details in terms of your flat mates too, personalities, hobbies and so on. *
Ok... umm... we are a pretty strange bunch who's hobbies have almost simplified down to being social, getting drunk and going out. An interest of mine is obviously Bitcoin.
Our personalities are really mixed, we have a bit of crazy, a bit of geeky, a little bit of gay and a lot of crazy (did I mention crazy?).
If I were actually to make this box - It wouldn't really have items of financial value in it... just bits and pieces from our freshers year (e.g. defaced lecture notes, stolen pint glass, lads mag - dont want to give too much away though).
I would also send a couple of beers in the box if weight allow? Im love a nice ale so I could send you some proper stuff.
Hell, id send you one of our traffic cones if it was easy to post!.
I would definitely put time into working out what goes in said box!
Just something I came across when I did a search for "bitcoin" on craigslist.
