rewind to two weeks ago, I've had a stressful day, DS is grumpy, we're on our way home:
DS "are we going to Tesco?"
me"no we're going home"
DS 2but I waaannnt to go to TESCO!!!!"
me "well we're not going to TESCO, we're going home"
DS (with an increasingly whiny voice) "but I want to go to TESCO!!"
me "well we're not GOING"
ds "yes we are, I'll make you go"
me "no we're not you can't make me"
ds"I'll be very cross with you if you don't take me"
me "I'll be cross with you if you mention it again"
etc etc
you get the picture.
I prefer the opther way! much less stressful all round, now just have to remember to use it...
