I came across an article about this new internet enabled pillow for couples in long distance relationships which glows when one partner lays his/her head on it it and lights up the other persons pillow, it lets you hear each other's heartbeats by plugging in earphones and basically tries to simulate an intimate interaction between people that might be in totally different continents (I'm sure you get the picture).
This got me thinking of how much we take our loved ones for granted. Hubby might just upset you and you give the silent treatment, wifey might get back from a long trip and you realise that is the first time you've hugged in ages, we might not remember to hold the hands of our old parents (if they are into that sort of thing) till they are laying in state or just sit and listen to their long stories of recollections of the 1960s.
