maybe she likes real life rollercoaster rides. she like the excitement of danger, but in the back of her mind, she knows nothing bad could ever happen. rollercoasters are always checked and maintained properly to avoid any problems. but maybe she's afraid of emotional rollercoasters. maybe, deep down, she's just a scared little girl. she pretends she's strong enough and climbs on board the rollercoaster. everything's fine, as long as things are looking up. but the second things start going downhill, maybe she doesn't have the guts to stay on the ride, and she just ditches. it's always been like this for her. once things start looking bad, she just leaves. maybe she's afraid that once things go downhill, she will crash and burn into the ground. maybe, he's teaching her to see that yes, things will go downhill, but that doesn't mean that she will crash & burn.
maybe all she needs is to learn how to hold on.
