down the memory lane 2

let me continue on my previous theme:  since time is not a variable but WE people are (my private opinion), what possibilities are there to review our relationships with our kith, kin and friends. Let us consider the tools we have:
Offer benefits like Gifts? Financial help?
Friendship? Travel together?
Partying? Clubs, Outdoor activities?
EL media: e.g e-mails, ?
Writing letters? Greeting cards?
Visiting each other?
