What about them not initiating contact is a negative? I can see why that'd be interpreted as a negative, but does it make sense for that person?

I know that I do a poor job of initiating hanging out but if I'm ever invited somewhere, I say yes 9/10 times. I like to do stuff but 1) I don't know what to suggest to do with others or 2) I want to suggest something however I am worried it'll be a negative experience and therefore I don't send out the invite at all.
