Teachers

Has anyone had the experience where you are in a store and you see an old elementary school teacher from like across the store and you know they saw you? Then you keep seeing them throughout the store and you know that they are looking at you because they know they know you but cant figure out who you are? Then of course you wind up meeting them at the register and you say hello and they play along like they know you until either they figure it out or you say something that gives a hint who you are. Well i had one of thoese experiences today... I was at the mall and i saw my old THIRD GRADE teacher and i knew she saw me and everything thing that i said up above happend and every time i saw her in the store she would be looking at me and then we met at the register ( Surprise!!!) and i said hello and she was nice and asked how i was doing ( i knew she had no clue who i was at the moment) then she asked what i had been up to.. so i started talking about archery and then she knew right away who i was and then she said " I had no clue who you were for a minute" HAHAHAHAHA
