I remember the movie "Cinema Paradise" directed by Guiseppe Tornatore: After 30 years absence a man returns to his childhood village. Actually he is terrible afraid, that all impressions might overcome him - but it doesn't happened. Well, of course, he is touched. He remembers himself as the small boy living in this place. But the man is through with the past. The presence is more important for him, even this presence couldn't have become like that without the past time in that small Sicilian village in South Italy.
A lot of expats might experienced in the same way. I did it too.
To become a real grown up - as a German saying goes - we must learn to forget many things of our childhood. is that really so? I guess, it depends... .
If we have waited long enough, we might be able to return "to earlier places" but WITHOUT melancholy or wistfulness. Good advice. But speaking about myself: I haven't seen my home town in Germany since 11 years. I am pretty sure, that a certain melancholy will touch my heart. Sometimes we'd like to reply with Bob Dylan: "It's alright, Ma, I am only bleeding!"
Yes, I must confess, I mostly got a melancholy heart while visiting places of the past. Maybe that's the reason, why didn't visit my home country since 11 years. Nothing will remain as in yesterday. Nothing can be found again in its origin.
Mabuhay Filipinas!
