Had my neighbor on the plane/bus/train been a chatty person, I would have been on alert for some time, it’s obvious, isn’t it? Some stranger trying to be too friendly. But once I’m convinced he/she is harmless, I may join in the ramble, cause I’m a talkative person as well! So maybe he/she could turn out to be my new bff, after all our existing friends we also strangers once upon a time 😉
