I'm just reminiscing about my last relationship trying to "remember the good times" I guess. Preferably nothing too sexual/physical because those are obvious. and I guess anything from your current relationship will work to. For example: I remember this one time she picked me up from work with a mutual friend of ours for lunch. On our way back to drop me off she was driving, our friend shotgun, and I was in the backseat. I just so happened to be sitting in direct line of the rearview mirror. All I could see in it were her bright green eyes and no other part of her face. We just kept locking eyes with each other with the passenger completely oblivious to what was going on.
