Back story is my parents had to look after our children for 2 days this Christmas, I did not ask them to as I would not do that and we had childcare sorted out. But DB and DSIL asked if our childcarer could have their 2 as they were stuck - my childcarer said no - so my parents offered to stay on and look after all 4 kids at my house. All kids under 8.
I asked my mother if she could refrain from going on the internet during the daytime. She will happily sit there with a coffee reading newspapers online and doing emails and quizzes for ages, and I feel uncomfortable with that whilst there are 4 kids in the house and my dad is ill.
At this point I'm fully prepared for someone to say I was BU to ask her this. Maybe I was. But I came home and found the computer and modem on, the mousemat moved to the left (she's left handed) and all the history for that day and the day before deleted.
I did not want a row, but just casually mentioned that she'd deleted all the history so was she on the computer. A complete, flat no. Denied it totally.
This is what hurts. If she had said "rest, you were BU and I went on internet to do...." that's one thing. But to completely lie isn't on I don't think.
She has form in not owing up to things unless confronted with incontrovertible evidence - eg the time she was opening my post and resealing it. She resealed one envelope with the address window blank then told me the letter was for me. Finally she admitted she'd opened it, and said it was because she was 'mad'. WTF
I wonder if this is why I can't trust people and have had interpersonal issues - someone so close lying like this.
W(ho)IBU?
