My ILs (who live abroad) have been staying with us for a month. MIL is the kind of woman who always has to keep busy, so she asked what she could do around the house. I said a bit of light weeding would be nice, mainly to keep her out of my hair as I WFH and she is constantly in and out of my office otherwise. Next thing I know, she and FIL have dug up our (small) lawn and ordered a delivery of posh turf to lay down. So far, so good. It was due to be delivered on Saturday but due to some cock-up only arrived yesterday. The ILs left late morning today, so I had to give up half a day's work to lay the lawn myself before it died on us. AIBU to grumble at the extra work this has caused and will now I have to look after the garden rather than leave it as un urban wasteland or are DH and I (as DH overheard them muttering) a pair of ungrateful wretches?
