When I sit down and have a cup of tea and a biscuit on the couch in the evening.
Not to get all Gregg Wallace on here but start my day about 6am and in between kids, commute, job, dinner, taxing kids to sporting activities and working in evenings, it's probably 9-10pm when I get to put the laptop away and know the kids are settling down for bed.
Sitting down at that point, normally with the missus, having a cuppa and a biscuit watching something on the TV brings a smile to my face. Love it at the weekend too. Family film on a Saturday or Sunday evening once all the chores are boxed off. Bit of popcorn, sweets, maybe a drink. Simple things but the best things.
