Its the same in my house too. My lot are 14, 13 and 10. My esldest (boy) keeps to himself and really isnt a problem. The other 2 (both girls) are at it hammer and tongs, day in, day out. Telling tales, causing trouble, I agree 100% with you about having had it up to here!
They even argue about whether or not they were arguing!
I have told them eaqrlier this afternoon that I am hearing no more of it. If I do then each time I need to tell them they are gonna lose a privelege AND a Christmas present.
So far so good....
There are no strangers here; only friends we have not yet met
