In laws staying late

Lou
This is just a rant really but i want to know I'm not alone. My partners parents are both retired, one being deaf and the other hard of hearing. They like to pop in or see us at least every 2 weeks which is nice, however when they come over they stay until just gone past 10. I work as a paralegal do I need to be fresh every day and on it in order to avoid my clients falling into a bad agreement so I'm in bed by 10. On top of leaving late I'm mentally switched on as sign language is not something I'm competent in but learning so I'm sitting there concentrating. In top of this, last night they called at 10pm. What the hell. Then my partner ignored and his mum Sen a text saying "we are coming over on Wednesday at 8pm". I mean we have plans and you stay too late arghhhhhhh.
