Both my parents lie to me. I'm in my late thirties with 2 children, they are both early 60s. Both haven't been very supportive parents over the years, but like to offer help which they rarely follow through on. They will lie to cover up their broken promises of support (I'm also a single parent).
My mother often drinks too much and we have an agreement that we will not speak over the phone unless she's sober. Recently, when I have spoken to her I've sensed that she's been drinking alcohol due to slurring and she has adamantly denied it. Even said she was taking offence at one point. Then I discovered that she has been lying. She has been drinking again and calling me.
My Dad will offer all sorts of services: gardening, pet care, watering plants, DIY.
I have suspected that he hasn't really been watering my plants when I've been going on holiday for a few years. Then I had a couple of discreet cameras fitted and didn't mention it. Nothing to do with him but for security. Surprise, surprise, he was lying about watering my plants. He came once during the week I was away after telling me he had been 3 times. He has also lied about calling over to let my dog out when I had to work in the office one day last week. I wish he would just be honest so I can pay someone else to do these jobs rather than lying about them all the time! He just shouldn't offer.
If I confront him, he'll only have some other cover up story, some made up bullshit emergency story so why bother?
My mother will lie about where she's been when she changes arrangements with me. I always say to her, just be honest, I can deal with the truth. Just don't tell lies. If you don't feel like seeing me and the children, just say so and I can make other plans instead of lying about working when she isn't etc.
I feel like I deserve so much better than this. I don't know any other parents who lie like this. I find it so weird and disloyal. I don't want to fall out with them at all, but I get more honesty from my kids.
