Easy to see it as expression of coming out. Or as need of other in terrible crisis. As deep loneliness of mental problems. Or as defy of isolation.
Each has his perspective but exactly this detail makes Come to my Window exceptional. Because it reflects a state - depression - hopelessness- tired resignation. And it explores, in honest manner , that state who , often deep hided, lives for very long time in your mind.
In short, just an useful song, more than cry , precise self definition and pledge for honesty to yourself and fall of silence.
Inspired video. Admirable interpretation of Melissa Etheridge.
