I once worked on a desk opposite a guy, who had often his finger in his nose, searching, finding and taking out.. you know.

After weeks of hesitation, once I told him: "Please, if you need to do it, do it in the bathroom". He said "Ok" and that was it.

It is a sensitive topic, just when writing this I have doubts whether to post this message or not.

But those things are just here, and if you act out of kindness towards the person, seeing how may he/she suffer because of that and by having a discussion or drop a few sentences on the subject, you are actually helping the person as well.

I guess it is better to try than to alienate that person in our mind and the longer it takes, the harder it is to start the discussion.

Be rebel! Talk about those things! With kindness.
