Some relationships are like Coke.. they are sweet, hard hitting, full of gas, give u the caffeine high, but can turn toxic very quickly.
Some relationships are like cocktails.. they look sweet and innocent but are actually quite intoxicating.
Some others are like pure alcohol.. you know, when you take the first sip, that you're in it for the intoxication, and that it wont last too long. And sometimes, you get addicted to them and keep bobbing in and out of consciousness.
Some relationships are like canned fruit juices.. they appear to be very good for you but are, in fact, artifically sweetened.
And some lucky relationships are like water - tasteless, odorless, very imperceptible in your life, but as essential as water... and like water, they make up most of you.
