Do you have family members that you purposely don't speak to?

I have never talked to cousins from my father's side. It's weird but that's how it is. My family is pretty reclusive and asocial but they're on entire another level. There's about 10 year difference between us so it was pretty understandable when we were kids but nothing changed over time. Whenever we came for a visit they closed themselves in their room. If they came out they sometimes barely acknowledged they had a visit, just went to another room to grab whatever they needed and headed back to their room...Sometimes without any greeting at all. 😅 They are like total strangers to me. If we had to converse for some reason neither of us would know how to start and what to say.
