You're, not your!
And yes, it's normal.
My wife always brings something to read and I'm patient when I'm with her when she is shopping. If convenient I do my photography alone.
I stood out in the blizzard today with my speed graphic doing some handheld photos in the downtown. I focus with the ground glass, close the metal hood, put the film in, review settings, cock the shutter, pull the darkslide. Then I stood motionless for about 3-4 minutes looking through the viewfinder waiting for a person to walk into a particular part of the composition. The snow and wind was so nasty, almost nobody was out and about walking. Normally, someone would walk where I wanted every few seconds and cars and trucks would be where I didn't want them. Finally after a lonnnnnggg wait, I saw what I needed happening and took the photo.
Man, I have pretty much sworn off snow photography after last year. And yesterday has only served to bolster my resolve.
No, I pretty much venture out solo because anyone who would go with would grow very tiresome at the 20+ minutes I generally take to make an exposure. And there are usually more than one.
I spent most of yesterday out photographing as the big East Coast storm was winding down. Exposed a whopping five sheets of film in five or six hours of faffing about in the snow. If you'd been with me no doubt it would have been you saying that I take (much) too long! ;)
Snow photography is for the young and the touched-in-the-head. I ain't twenty anymore. And, contrary to popular belief, I ain't that touched in the head.
Next time just show your friend the expiration date on the box and film and say you have plenty of time. Of course, if you use expired film...
