I like Costa. The atmosphere is relaxed but sophisticated, and sitting inside at a window table (in order to people-watch) on high stools with a friend whom I had not had a catchup with in a while was extremely pleasant. Of course, the hot chocolate with marshmellows, cream, and chocolate sprinkles added to this effect!
But even more than my liking of Costa, is my liking of catch-up chats. Most people know this. I'm the inquisitive (or nosy, take your pick) kind of person who likes to know what's going on in other peoples' lives, and who likes other people to know most of what's going on in my own. I think that it takes a lot of trust for two people to have a proper, two-way catchup, and it builds the relationship between them. Knowing what is going on in someone else's life helps to understand them better as a person, and with understanding comes stronger friendship and companionship.
As for sharing your own life, burdens are much heavier when they're not shared. Obviously, catchups are not about sharing every single thing that has ever happened in your entire life, but the important, big, relevant (and appropriate) things are often better shared, because it means that there is at least one ear out there to listen to you. This applies to good news and updates as well as bad or upsetting ones.
I'm a firm believer in catchups. Especially ones in Costa Coffee.
