Taking horse out of routine?

[cobface]

For the final 2 weeks of the summer holidays i have no child care so decided i will ride of an evening instead after work (around 730pm) mare thrives on routine and normally gets ridden early afternoon.
End of the week we have a XC schooling session and have arranged for children to be looked after.
Went down last night and mare was sharp as a tack - took her out with friend and she just bucked constantly and was really on her toes. She bucked at one point and ended up kicking my friends horse luckily she was fine.
I dont want a repeat of last night as shes no fun and makes me feel nervous......but she needs to be ridden 5 days per week or shes a monster. So, do i persevere with the evenings, just ride at weekends and give fridays xc a miss (if i dont ride her til friday she will be too much) and wait until kids are back at school so shes in her proper routine again?
Thanks
So, this is what she thought of me last night

at the pics!
i would persevere with what you are trying to do and actually make a concerted effort to try and get your mare out of a routine- as you have seen it causes problems when you make changes, if your horse has no routine then it can't get stressed about it
