I don’t like shaking hands with people – I don’t know where their hands have been.
And I definitely don’t like being kissed by people when I greet them – it’s totally unnecessary. There’s nothing wrong with saying hi, how are you and smiling nicely. Unless it’s family because that’d be a bit formal.
But the people who really annoy me are the ones who come in as if they want to kiss but then turn their heads at the last second so it’s like you have to kiss them on their cheek when they were the ones who wanted the damn kiss to begin with. Then you just have this awkward brushing of cheeks moment because I’m not kissing them.
