Search Results: asked her how many children

I met my father three times in my life, last time I saw him I was about 12 and he just dropped off the radar. Never took an interest in me or paid child support. He is a complete stranger to me.
Last year I took an ancestry DNA test and found two half siblings I never knew i had through my father. One is still coming to terms that I am her sister (we haven't spoken since Jan), the other sister I met in person and we are getting to know each other.
She has had some contact with our father sporadically over the last twenty years (she was adopted at birth and found him as an adult). Through her I have found out a lot of stuff about his family and his life. He is a convicted criminal, has a drug problem and apparently was/is obscenely wealthy.

My sister has hinted that we should ambush/confront him (as he never told her about me) together.
On one side, I would like to ask him questions about the family, namely if there are more siblings and about the grandparents. He is also getting older and people die, plus his lifestyle is rough. This sister has also had a falling out with him, so she may not be able get any more info about the family from him. On the other side, I really don't know if I want to waste my time on a piece of shit that could suddenly fuck up the life I have worked tirelessly to build.

So I am kind of unsure what to do. What would you do if you were me?

I mean the right to have freedom and democracy. Where I live and in other countries you can only go out if you write on a paper why you left the house, where you live and so on. The reason must match a number of reasons the goverment considered to be justified. If you don't have the paper or have a tiny mistakes on it you are fined for more than the average salary (not the minimum...). Lots policemen make abuses and give fines for the smallest thing. You can't even go out at a local shop without risking a fine. Also, they closed the dentists' offices, women couldn't find a place to get an abortion anymore. They also want to force us to wear masks in public transportation (and other public places) where we don't have air conditioning for the whole summer... Of course, nobody asked us anything, though we are supposed to live under democracy...

I am not complaining they closed the unnecessary bussiness, but it feels like we are in home arrest. We have about 14k total confirmed cases and 850 deaths (most had serious illnesses...). The economy downfall and the isolation has affected way more people. We also have more cases of measles, but nobody talks about it. And you may say that less people die of measles, but mostly children are affected and they usually don't have other affections, so of course the mortality is lower. And the sad part is that they are probably going to do the same in autumn...
