There's a very typical saying in advertising: "If an idea is good, you should be able to explain it in the time it takes for an elevator ride". So I start thinking about what idea someone would get of me in that exact situation:

(Awkward silence)

RANDOM PERSON: (coughs softly, looks up at the ceiling)

ME: (smiles and looks up at the ceiling too)

R.P: Hot today, huh?

ME: Yeah, really hot. At least it's September now, not much left of it.

R.P: Oh, where's that accent from?

ME: Argentina. But I've been living in Spain for six years now.

R.P: Oh, nice. So what do you do here in Madrid?

ME: I work in advertising. I'm a creative copywriter.

R.P: Oh! Tell me, did you make that car commercial, the one where it drives up the mountain?

ME: Mmm, no, that wasn't me.

R.P: Ah, well, I really like that ad.

ME: Yeah, it's nice.

R.P: Yeah... (coughs softly, looks up at the ceiling)

(Awkward silence)

If this didn't give you any ideas about me, great! Let's meet in a elevator, or anywhere else, and share ideas.
