LOL Jorge - I get that A LOT!
I noticed that I did that to someone I saw at a cafe not to long ago - they reminded me so much of an old friend of mine. I stopped myself from projecting those picture images onto him though because I realized that I wasn't allowing him to simple be his life-expression in that moment...I was actually enslaving him, as well as myself, by existing within and as picture images and memories instead of being here, fresh. So, it could be cool to write out the point, see what you perceive me as in relation to your friend - might reveal some things. I know it did for me at the time.
