Sexy girl on a nearby bench (non-straight thread here)

Hesitating, Derek looked around. He noticed one attractive Latino girl on bench nearby. She was in her late twenties and was dressed rather sexy than comfortable. Derek smiled and checked her stats on his phone.

"Oops!" mumbled he, as there were no icon of that girl. He switched to map view and fond himself in the park. The symbol, indicating closest person, who should be that woman, was grey and inactive.

"What the hell?" Derek was confused. He tried to tap, tap and hold that icon but it didn't work. Accidentally he slide top side of the screen and new menu scrolled down.

"Map view, satellite view, icon size," Derek was reading items until he noticed small symbols in top corner. There were three circles - red, blue and purple, with small additions. The red had a cross at bottom and was definitely active, blue had arrow at right top and purple has both.

"What does it..." started mumbling Derek but suddenly he shut up.

"Damn." exhaled he. He looked again on that sexy girl and on his phone. "That can not be." said he to himself and pressed purple symbol.

At the same moment grey icon on the phone's map next to his location activated.
