My mum and dad separated over 20 years ago, acrimonious at the time but as the years have passed they have come to tolerate each other and for family events (school plays etc) will spend the evening in each other's company.
Mum for last 10 years has owned a hotel in a tourist destination. Dad regularly visits the destination but steers clears of mum's establishment.
Dad this week is now staying next door to Mum's establishment in a middle of the road hotel, i.e. not a cheap place nor the high end of luxury so no obvious reason for choosing it. He doesn't want Mum to know he's there.
I'm now thinking this is a case of all the hotels in all the resorts you choose this one.
AIBU to wonder what my dad's up to - if anything?! [Suspicious mind me]
