My pots and pans are going missing and so are my utensils. I brought it up to my husband after I searched my entire house and he thinks his sister may be stealing them and putting them in her room. She keeps talking about wanting to move out but she has no pots and pans or anything to move out with. My husband said he's going to search her room while she's at work and if he finds our things he's kicking her out. We work really hard for the things we have. I just spent another $45 on more utensils because my other ones have vanished. That $45 could have been used on gas or my daughter or daycare. Pots and pans are expensive I don't have money to replace them. I'm hoping she's not taking my dishes but if she is I'll be so disappointed. Especially because we are helping her when no one else wants to.
