Just shows best not to vary established routines!
It is exactly that kind of behaviour that arouses suspicions.
I'm a bath before bedtime person, but Mrs T may have one in the day, and might
be wondering why I changed my routine, although requests for a shared bath always fall on deaf ears.
But it's other behavioural traits that can get noticed, like shaving more often or at a different time, new pants, a sudden improvement in personal hygiene, and the old one of coming home from work late/mobile off. Mrs T knows I will not answer phone when driving, so my excuse is that phone was on silent, so didnt realise for 45 mins. Works well.
I never punt locally, always 20-40 miles away and there is part of me that twitches about being involved in an accident - why were you there? would be asked - or getting a speeding/parking ticket. Consequently, I try and incorporate a punt when I have a legitimate reason to be somewhere, so no questions asked, so the 'cover' story is genuine.
As for phone numbers, as my punting phone is wiped post punt, the numbers of just 4 girls I see often are listed in a Word document, but by town and part reversed, with a suggestions that they parts numbers for a BMW Z3 sports car, and that file is password protected, and hidden several folders deep. Cant be too careful.
It's not easy to cover your arse 100%.
