@Jacopo I’m sorry to say that that doesn’t work either - you’d expect it would, but all it does is call out what you already knew and you get an immediate answer…
I’ll try not to give the full boring details, but we lent my sister some of our ‘big’ baby things for her newborn - (eg baby rocker chair, baby swing, Walker, Bumbo chair with activity tray) with the very clear message that it was all to come back to us (we were planning to try for another baby imminently).
After her having the things for nearly a year and me being very pregnant by this point I sent her what ended up being quite a few messages - all of them totally ignored! She even blocked me, which started ringing alarm bells.
Eventually, following much stress and attempts at contact, we managed to arrange (via my mum fgs!) that we would pick them up from her house on a certain day (we live a couple of hours away and didn’t want to chance it by just turning up). We got there and all of our baby things had been left outside of her front door in bin bags in the rain. Everything was filthy (had been lent in immaculate, as new condition). All of it was there except the (expensive) baby swing. Husband hammered on her door for a while and I called and messaged her. She was clearly in her house but wouldn’t answer the door or her phone. We eventually left, convinced that she’d sold it.
A week later, it transpired that she’d put the baby swing outside the front door later that same day (in the rain). We were on our way home by then. The baby swing was STILL sat outside her front door at this point… A week later… In the rain.
I don’t talk to my sister anymore - all of this was the straw that broke the camel’s back.
PS my sister once went on a European city break with a friend and had no money in her bank account. She had the friend fund her.
