Parents causing problems

Landed in Kuala Lumpur, Malaysia, after 8 hours on Malaysia Air. After we got off the plane, my dad had to go back in the plane to get the duty free, and my mum had to go back in the plane to try and find her reading glasses but she couldn't find it.We are waiting for the cleaners to clean out the plane and find mums glasses.I'll keep a better watch on them.
