When you are walking past others (in a street, in a corridor, walking past someone's desk, etc) do you make eye contact with them and smile? If so, do you do this with strangers and colleagues?
I only ask as recently I have realised that I avoid looking at others when I walk past them. I think it is fine in the street with strangers but I noticed when I was in a new environment for work which involves walking around my building lots (rather than just sitting still all day), I feel really awkward when I walk past colleagues. My default reaction is to look down to the floor or start fiddling with whatever I am holding or something and pretending I don't notice them but I realise that probably comes off as rude so I now make myself look up at others and smile. I was surprised to see that every person I looked at was already making eye contact with me and now I feel so rude and embarrassed for all the times I unintentionally brushed people off.
Sorry for the weird question. I grew up very shy and whilst I have largely grown out of that shyness I think this is perhaps a relic of that former self. Also where I grew up and at the secondary school I attended looking at others was seen as confrontational so that may have contributed to this a little too.
