That guilty feeling

I take my role as mum very seriously, I think sometimes too seriously! I had to wait in a mobile phone shop today for 4 hours, yep, 4 hours with a 2.5 year old and 3 month old! Luckily my wonderful mum rescued my poor toddler who didn't wish to spend her day in a boring phone shop (she was so well behaved though) and my wonderful little man who just slept and sat in my arms the whole time- my back now paying for it! I felt so horrible that my day was wasted standing in this shop talking to useless people on the phone when it could have been spent doing things with my two beautiful children! I cried the whole way home along with my 3 month who was obviously over it all too! My point is I felt so terrible and so guilty all afternoon because I spent so long in that damn shop! I know my kids won't remember or care as I'll make it up to them but my heart hurts because I love them dearly and love every moment together so to waste 4 hours of that time is just heart breaking!
