I view it not that 'they' installed them, rather than 'you' installed them. Approach your difficulties from a new angle, ie, think outside your box and learn a new way to deal with it. I ought to know. My family lives 7 timezones away and have all fallen out with me.
In my view, I am the only person who can guarantee to make myself happy or unhappy.
Try your MIL rings to ask aboput weather her suitcase is okay. Gets an answer from me as DH with plumber and then going to builders yard. I say is there anything else or does DH need to ring you back and she snaps I'm sure DH can spare ME five minutes. AHHHHHHHH
