@Krystina23040, I've had to separate this out because the website wouldn't let me upload my full reply. It should continue:
Going away, I have to make lists, decide what I can do without, make sure everything I am taking is ready to go, then, the day before at the very latest, start packing, ticking off my list as I go and working out what is best to go where in the bag, rearranging as necessary. Tom, who was in the merchant navy, going away for 9 or 12 months at a time, would leave his packing until about an hour before the taxi was due to collect him, then everything went into the right place in his case and bag and he would be done well before the taxi arrived. He didn't need to think about it, having done it so often. Nor would he ever forget things like passports, wallet, glasses and so on, which I know other people do. He had a little mantra to check he had everything before he ever left the house to go anywhere, whereas I would be wondering if I'd forgotten anything.
As I say: either practice or it's a man thing.
But then, I always want to be at a station or airport well before the allotted time, Tom would leave it until the last minute and then run to catch a train, sometimes crossing the track in front of the stationary train to catch it (you could do that way back when). That was the first time we ever fell out over something. Coming from the south, I wasn't used to such behaviour.
