The first thing to understand is that being a vegetarian is actually a private matter. I'm still taken aback by the question " then what do you eat?" and am embarrassed as I struggle to produce the weeks food diary. Its not that I'm ashamed of what I eat, but its none of anyone's business. I imagine I would have a similar feeling counting up how many pairs of underwear I went thru in a week. The only reason opening someone's fridge is more socially acceptable than opening someone's medicine cabinet is that people keep beer in their fridge.
