Actually stupid is the guy talking and thumbs up for that girl. If you are such ignorant retard you don't understand what she is talking about after second sentence, you shouldn't even buy iPhone 6. It's true it's usually dumb-proof, but not 100%. Also intelligent person would start a conversation regarding buying something like "Hello Mrs. Xxxx, I would like to ask you about the item you sell. Do you have a minute? Is it still up for sale?" etc. If you start conversation like this poor fcker, then your parents did a bad job. That girl is probably gold.
