yeah, i've done that before too.....my 14th birthday....my mum met me from the river after i'd been rowing and said we were going out to lunch and to spend my birthday money. got to pizza hut, walked in and there were 2 of my close friends standing waiting for a table. so i went over and said hi and how i was having lunch with my mum etc and they fell about laughing. turned out my mum had arranged for them to be there and go out to lunch with me! what a fool i felt! sadly, one of them died later that year. it was one of the best days I had with her, so my silly reaction just makes for an even better memory
