Something I have observed (from myself and others so not a criticism!)
When people are actively trying to make friends, it shows.
The 'energy' is different. When you're the person trying to make friends, it feels organic, normal, like you're just making an effort to be friendly.
When you're on the receiving end, it can land differently. The effort doesn't seem to match the length of time you've known each other or how well you know each other if one person is trying to progress a friendship and the other isn't really interested for some reason.
Eg the woman at your daughter's club you sat with who now sits in her car.
Why is that? Maybe she has her own personal reasons? Maybe she didn't want to sit with the same person every week? Maybe she didn't feel you had much in common? Maybe it felt a bit intense?
I'm.not saying you're doing anything 'wrong' just that your approach might not be right for everyone so the options are to either do a bit of self reflection and see of there is anything different you could do or just write that person off and not take it personally.
There can also be a tendency when you're actively.looking to make friends to (want to) become friends with someone just because you've spoken to them a few times rather than because you actually gel with them.
A bit like online dating when people ry to make a relationship with someone they're not really compatible with just because they had a pleasant enough first meet with them and there's no one else they're interested in at all 😉
If that makes sense...
