my sister inlaw allways over stays her welcome, she turns up in the morning and leaves late evening, she has a 2 yr old who is into everything and wants all the attention,and as i won't smoke in front of the child i end up spending all day in the kitchen,whilst the rest of my house is overtaken,i feel she uses us for a baby siting service and last weekend i told her so, she hasn't been round since, sometimes you just have to tell people if they don't take the hint.
