There i walked dowwn the street and saw ABSOLUTELY NOTHING. I just mentaly, and visualy 'blacked out' everyone who I thought was a woman. I once did this to my Rosh Yeshiva Shlita (I misstook his frak for a dress, and his 'build' for a woman :D), he kindly inroduced himself, and we all had a good laugh! In EY I went to shabbos meals at the home of somebody with girls my age, and never once saw what they looked like! Although when they invited me to be a ben-bayis by them, I didn't want to do that (I felt it would end-up being an uncomfortable arrangement)
But there all the girls dressed like a 'bas melech', and they acted like it!! So for me to be pogeim that and look at them, is something I have almost no YH to do. You see I have a much easier time being Shomer Einayim with tzniusdik gils/women.
But in America.... I feel like a nutjob, the women sidesep INTO my field of vision, TRYING to be seen. I feel like an idiot every time i walk to the counter. I feel like a dufis every time I need to ask a woman for something! They all say things about me behind my back, and people LOOK DOWN on me for being shomer einayim! It's a whole new ballgame, and I stink at sports.
Additionaly I learnt in a very shelered city in EY, the only chilonim where kids going off the derech. And 90% of them are boys. So there was no real pritzus, except for the occasional lack of tnius. My nissyonos where by the shabbos table, and that was about it! I had a reputation for being shome eianyim, so the avreichim I ate by would be surprised if I did otherwise (they where also impressed that I didn't look even once at their wife)
