Lol, I actually had a similar experience when I bought my OEM nose mask from another member. We spent about 20 minutes on the phone while he "felt me out" to see if I was only interested in buying it to (a) hoarde it in my closet for later sale or trade or (b) flip it on eBay. Fortunately he believed me when I said I wanted to actually use it, but even then he asked me to post pics here.

There is a reason we say "welcome to the obsession" to new members.
