Any good chat up lines/things to say when approaching guys?

[just me]

Here's the thing, I'm fourteen, female and single. I'm still in love with my ex who broke up with me for another girl 2 months ago which is really sad i know.
My parents are dragging me to the lake district for a week which is good coz no one knows me and i'm never gunna see these people again so i see this as a fresh start.
My aims are to spend the whole week flirting with a guy and to get his mobile number- this will help me get over my ex if i can find someone else to focus on and i am quite good at long distance but the whole point is to get over my ex.
I'm pretty shy to start off with so approaching this guy would be pretty hard but after a while i am good i gotta say but i need good chat up lines and just things guys would find interesting. now. please............. thanks soo much
