I feel so mean but I just dread my DC asking, ‘Mum, can we come in for a bit?’ and bringing the local children in. They have a ‘den’ to use but even so... I don’t know why it bugs me so much but it just does! Perhaps the fact i’m a secondary teacher locally and so know some of them in that capacity too has something to do with it. I’m off and like to slob in my scruffs with no bra and there might be piles of underwear lying around just having come out of the washing machine/waiting to go in...! And then they might want a drink or food and i’ll Have to get up off the sofa and sort it! 
Lighthearted(ish!) and I usually say yes through gritted teeth but am i the only one who dreads this request?
