Over-friendly 5 year old

[Romewasntbuilt]

My 5 year old will speak happily away to all adults and children alike.
However, she will make a beeline for the same mother and child from her school on the way home from school a couple of days a week.
The child is in her class and they do not play together. The child is quiet whereas my child is loud and chatty.
The child has made it clear that she doesn't really want to speak to/walk with my daughter and reading her body language and facial expressions, I'd say she finds her overwhelming.
However, my daughter will try to talk to her mum about all sorts of things. The Mum is very serious and does not seem keen on making conversation at all and more recently has begun walking ahead quickly away from us despite my daughter being in mid-sentence. They could well be in a rush to get home, so it may be that I'm being overly sensitive about this.
But, I have noticed that the Mum will make a lot more effort with any children that her child is friends with and their parents. She has a close circle of friends who she does make an effort with, which is why I must be taking this more personally.
My daughter has now noticed that the mother and child do not want to listen to her and she has asked me why.
Do I explain to her that it's because she's being overly friendly with people, or do I explain that the mother and daughter do not wish to chat to us and some people can be like that? She has also noticed that the mother and child will sometimes happily walk home with other children and parents.
I'm not sure the best way to approach this?

Just from what you’ve said, your child sounds friendly and confident, but not over friendly. I’d just say we can’t be sure what other people are thinking, but maybe they want to talk to someone else, or be in their own, and that’s up to them. To not worry about it, and find someone who wants to talk or play etc.

My DS can be like this but he can also be on the opposite side and be making it clear he doesn't want someone to talk to him.

I think the mum sounds hideous to be honest, your DD is 5 and she should humour a small child who is just being friendly. Or at least be subtle, make a little excuse in an apologetic way etc. Rise above.

Thank you. I have subtly spoken to my daughter about social cues, but also explained that the mother sometimes doesn't like talking very much. I've said that she's not a very good person to talk to because she's grumpy and some people are like that.
I didn't want to place blame on either my child's chatter or the mother, but I've made it clear I think that it's not just her fault for talking.

Sounds like your DD is intrigued by their lack of interest. Don't take it personally, the school gate is a funny dynamic.

My DS was a quieter child and would have been very overwhelmed by this sort of interaction. If they've been at school together, it's likely the other child wants a bit of down time not to be followed home. If this had happened to us, I think I would have reacted in the same way, to try and make it politely clear you didn't want to talk. This mother and child are clearly giving you the message they don't want to talk so give them some space. I wouldn't call them grumpy.. they just don't want to talk.

If your child is making a beeline for a mother and child whose behaviour is telling you that they dont want to know, then it is your job to stop her. It is also fine for her to start learning social cues and not to pester people - calling them grumpy is disingenuous.
