My BF and I work in the same industry.
In order to do our jobs properly we need to own a key piece of kit.
For the past two years she has been borrowing mine. I must have lent it to her 20 times. She never voluntarily gives it back - i always have to chase her. It's not malicious she's just scatty and disorganised.
Every time she says it will be the last and she will definitely buy her own. The last time she had it, I had to chase her for its return and ended up having to reorganise my own work because of it.
she's just asked again this morning and I said no, sorry you can't keep diong this.
She's just emailed me saying she feels let down and that she has lost the commission because of me.
Now I feel awful.
