@Schooolm OP, you sound very much like me - a sensitive soul, who soaks up everything in their environment and notices every single interaction. It is often a strength; like you say, you make eye contact and involve everybody in a conversation to try to ensure nobody may feel excluded. But often it causes us to over-analyse and assume there must be something wrong with us when we notice that others won’t (or more accurately can’t) do this for us.
I have spent just over a year doing the school run and have had many interactions just as you have described. It did get me down at first, but I worked on what others have already mentioned - bright and breezy pretending not to care while still being friendly and polite to all. I am now getting a lot more warmth and friendliness back from those who appeared quite indifferent before and have also met a couple of new, lovely parents I just hadn’t really crossed paths with. We’re not best friends or anything, and I’m sure we won’t be in touch come secondary school, but we are friendly with one another, and it now does not feel as much of an ordeal every weekday 😂
I did find hosting my child’s birthday party, then being invited to others in turn, to be a bit of a turnaround point in getting to know some parents better. Being helpful via the WhatsApp group and sharing frustrations at the absurdities of school admin (expected of parents, that is) has also helped to break down some barriers. (Not sure if you’ve got something like that set up?)
Continue to smile, wave hello, ask “how are you?”, start conversation where you can about absolutely anything - school, child, work, weather, the highs and lows of parenthood - to break the ice. Just continue being the lovely person you come across to me on this thread as being! Sometimes it just takes a bit of time to build connections 🙂
I do agree with others who have pointed out that often parents are knackered, particularly at pick up, and have no social battery left (this was actually me today 😂). There are also those that really are drop off/pick up, nothing more, and that is fine - people have busy, stressful lives and may just not enjoy small talk at the school gates.
But I get why you are upset, because your experience was two mums happily talking to one another - who obviously don’t mind the chit chat - and not including you. Some adults naturally gravitate to one another and are not quite as attuned as you are as to when another person is on the sidelines feeling a bit left out of things. I promise it is nothing you are doing wrong and they don’t hate you - they’re just not noticing these things as you do!
