Thanks for the suggestion. The shot was taken very close up, so there isn't enough room in the original image to make it a square crop without losing either the light on the back or the face altogether.
The lighting is great, it really highlights everything wonderful in this photo. I think I would have cropped off the top part with all that blank wall space though, it just doesn't seem necessary. Plus, the artist *cough cough I mean "kid" cough* in me wants to draw your outline in crayon, marker on some red horns and the tip of a tail, watercolor a highway that winds around the wall and blends into and keeps going across your back, or something fun like that! LOL
It depends on the person and the situation. I like my space, but with good friends I like close conversation. There's something intimate (and not necessarily sexual) about several friends having a close conversation, especially over a few drinks.
Now, with strangers it definitely depends on the situation. If I'm in, say, a hardware store and someone gets within my personal space then I'm going to first move, and then if it continues we're going to have words.
If I'm at a bar, and someone(s) approach me and are gentle then I'm usually very receptive. And by that I mean I would need to perceive their approach as an invite to good conversation...or whatever. I would certainly be even more open to that if it was my wife and I out for drinks and the approaching stranger(s) were engaging us both.
So, pretty much normal parameters then. Most people don't like feeling alone or surrounded by emptiness unless they have problems with being easily overwhelmed or touched. My son is Autistic, I have a friend who's an Aspie, and I have some sensory issues myself, so I feel like I'm maybe on the middle ground between spectrum disorders and not. Or at least I understand them better than some. Issues are definitely way more manageable than a disorder though. In general though, I just like to ask people lots of questions. I learn new things, hear different perspectives, etc.
