Taking things personally

hi there, 

im new to this site. My 11 yr old son is in the process of being assessed for ASD. Now I know the traits of high functioning ASD / Asperger I recognise  My partner of 30 years probably is also on the spectrum. I have loads of questions!!!!! One that came up tonight... is it a trait of ASD to take things personally and not be able to laugh at yourself ? Given I’m now aware of these traits during a conversation tonight, which was very light hearted my husband basically took the huff because he didn’t know what a phrase was. I couldn’t understand why he was in a huff about it. He says he feels like I’m laughing at him. And is annoyed with himself which makes him worse. We were able to talk about it which was good. So is not being able to laugh at yourself a trait ? And does anyone have any suggestions as to how this situation can be managed without turning into an argument?
