Sometimes, we may not realize that what we are asking is wrong because we think they are neutral questions. We may just want to connect with people, but then, unfortunately, we ask awkward questions. There are some questions that, while they may seem like they're asking for more intimacy, can actually hurt people.
Some of them you can find here (to never do again) Why are you still… single?
Why do you look so tired?
how old are you
What university did you study at?
(When he may not have studied at all)
Do you exercise?
where are you from
Whoa, are you skinny?
What happened?
