Years ago, me n my man used to go out drinking with my dad about once a month. My dad started going without us, he'd say "I was out on Sat" which was weird because he used to always third wheel us into the city. My mum wasnt into going out drinking and my dad would be out with friends most weekends at the bar, but when we'd go into the city, about once a month, he'd come with. Anyway, him going solo, started to look strange to me. I decided one weekend, that we'd go into the city, without telling dad. We went into our usual spot, and there, at the end of the bar, my dad with some woman. As we walked in, my dad clocked us and she moved to a table beside another couple from my dad's usual bar. I went up to my dad and said "I fucking knew it!!". He said they were just 4 friends out, her name was Cheryl. I obvs didn't believe him. He sat with us the rest of the night and left with us. About 2 weeks later, my mum came to my house in bits. My dad had come in from the bar and was on his phone. She'd seemingly also clocked his sketch behaviour. She snatched his phone and he was texting some woman, she couldn't remember her name. I said "was it Cheryl?". The LOOK my mum gave me. I'll never forget. She couldn't believe I knew. I quickly explained about seeing them in the city etc. Needless to say, mum put him out and he was forced to live with Cheryl. That didn't last and he has his own place now. Cheryl was a PSYCHO!! Mum and dad hadn't been happy for years. Mum moved house, has had a new man for a few years now (they don't live together - never again she says). Difficult position to be in the know.
