But I also don’t think that it will be much improved by me walking her around empty streets being frightened of touching a fence post, holding my breath if people pass me or wondering if my picture is being taken for someone’s social media post about me being out somewhere I shouldn’t.
See it is this that is the difference across people. Not whether there is a NEED to do X or Y or Z. Life is not about us paring absolutely everything down to a fundamental NEED. I mean by that count all we really need is the very bottom layer of Maslow's hierarchy of needs - we need food in the gob, need to be safe from being killed, and need to sleep and drink. But that is not how we live life (usually). We try to make the best of circumstances.
The circumstances as I see it are to follow the rules which have been set - and within that do my best to live a full life, without breaking rules. I have a 4 year old and a 3 month old and a little dog. I could spend the entire time with the baby cooped inside my own house and medium garden arguing i don't NEED to do go out. But I do. I take all 3 - sometimes with spouse sometimes without - to the extensive woods behind our house, where we spend hours and do not meet anyone except the occasional speck of a walker 50 metres away or something. But even if they passed - I would not imagine holding my breath. I would not worry about my 3 month old. I would not obsess over fence posts.
We practice good hand hygiene, we do not meet other people, and we live our lives. Me, 3 month old, 4 year old, dog and spouse - those extensive walks/ambles in the woods are the reason I have been able to regain my postnatal physical health back, and to not get into postnatal depression - which frankly is a heightened risk when you are raising infants in a pandemic.
But ultimately life is not about living it according to the lowest barest needs. But if going out is leading to anxiety meaning actually holding your breath if someone passes - then obviously it is a very specific situation/anxiety rather than any generic observation to be made about whether one in general needs to go out or not.
