1) you look like your own younger sister
2) (from good friend's fiance)- mmm, mmm if you keep this up I may have to dump "fiancee's name here" (all done jokingly, but it made me smile and blush)- plus my DH was there and laughing too
3) (picking up a friend from the train station - we hadn't seen him in a year)- he just walked right past me (waiting by the area where they debark) and went up to my husband who was over sitting in some waiting chairs "Where's Laura?" (it was awesome, he didn't even recognize me, and the look of shock on his face was priceless)
4) former co-worker (ran into at the store)- "you look awesome, you must be so proud of yourself"

and quite a few more.. they really make your day don't they?
