LOL what a cheeky cah! 😆
Reminds me of when a young couple moved into a house near us/opposite us several years ago, (in their mid-late 20s, both work full time,) and their garden was never looked after much. They mowed the lawn twice in 4 months and it was like a jungle.
His dad came around to visit (and his mum too - they live 300 miles away.) The dad shouted over to me 'hello' and I said hello back, (I was weeding the flower beds.) He started going on about the nice weather, then said 'feel free to come and do some weeding for Ellie and Liam, and run the mower over the lawn, they're no gardeners! haha...'
I was like 😐
Then he carried on chatting about something or other. I went into the house soon after and brought out a leaflet with 'Jim's Gardening Services' on it, and said 'he's meant to be quite good, and not too expensive..' (Coz like fuck was I doing their gardening!)
He said 'ooh, no, they're not paying anyone. They've got their own mower, and gardening tools...' I thought 'oh, so they won't pay. They want someone to do it for them for free. Cheeky twats.' 
I'm 30 years older than them, (and so is DH) and we're even older than their parents, and the dad has the fucking cheek to say I can do their weeding and lawn mowing for them. Fucking jog on mate. I love my garden and enjoy doing gardening. But only MY garden - well, mine and DH's
. It's a big garden - corner plot - and is fairly high maintenance. I love it but it's quite high maintenance,
Doing anyone else's would be a chore.
Some people are unbelievable! I don't know if the couple asked the dad to ask us, or if he just asked. But neither me OR DH has ever touched their garden, and they've never mentioned it since. Them or the parents.
