I don't think it's bad. We all have different personalities. Some people are more sensitive than others. Also, some people do not interpret jokes the same way as others do.
yeah...cuz it's a joke.
Sometimes "jokes" (especially when they come with ditto marks) aren't jokes at all, but a passive-aggressive way of saying something. If you know it really is a joke, then don't take it seriously - unless it's in the "I'm really tired of the same old routine" way.
