People communicate in different ways. Some are good at staying in touch. Some are terrible. I am not great, but I do think I put a decent amount of effort it. Sometimes it feels very one sided, and so on occasion I have held back, and friendships have died a 'natural death'. The problem with treating relationships like transactions, and seeking balance, is that in proving yourself right, the victory can be pyrrhic. Balance can be overrated. There are always rubbish bits. If you focus on them too much, you can lose things that were precious. Everything has a price. Don't nickle and dime so much you destroy what matters.
