Does anyone else feel uneasy when adults use playgrounds without children?

[AAAaaaaaaaaaaBbb]

Am I the only one that hates when adults go to the playground without children? I know it’s a free world and they can go where they like but it makes me feel so uncomfortable. Like yesterday was sat in the local playground was only me and my kids and a group of 5 adults arrived with no kids, just makes me feel so uncomfortable. I realise im probably being unreasonable but I can’t be the only one that hates it

I always sit in the children's playground on my street with a book because it's the only bench in the sun. I hope no one think's I'm weird.
