I lived 2 years in Spain (Madrid, Sevilla, Granada & Barcelona)
Hung around a lot. After 1 year i decided to do an MBA. Went to Barcelona and didn't like the IESE school there. Returned to Sevilla and found a little school there and learned a lot of spanish in the process.
In fact the class was in spanish when i still didn't know one word. So i had to learn business spanish in 2-3 months.
How i did it? i was watching TV all day with talkshows. Read books even though i didn't understand them and spoke to people on the street connecting my emotions with words
So here goes my first lesson:
dónde está el baño = where is the bathroom
necesito = i need
necesito ayuda = i need help
cuanto questa? = how much does it cost
me gusta fumar porros = i like to smoke joints
no me toques los cojones = don't go on my nerves (directly: don't touch my balls)
dime = tell me
vale = okay
salimos esta noche = we are going out tonight
if you want i can do a youtube for it so you can listen to it
