My sister attitude is starting to get on my nerves, What do do?

Anonymous
My sister does not even live with my brother my mom or me. She is married and does not even live at home but still she treats me like Im a little kid and acts like an inspector in everything I post on Facebook. A comment, a photo a meme, if she feels what I psot is not like good she then has to question why I did it. I have to keep my FB account active for different reasons and if I block her or delete her she will get pretty piss off at me for doing it. I mean it is just a matter of respect and let me post what I want cause I never question anything of what she post, even if I found it also ridiculous or stupid. I am a member of a certain group on FB.

So my sister is member of that group and I als I am member and sicne she and I are friends on FB is the reason she can see what I post and I can see what she post.

I asked this helping a friend of mine who does not belong in this FB group and she is not a member so I ask the question on her behalf. I did not see anything wrong on that question I asked. Well my sister thought the opposite. She read I posted that question and on Whatassp in private she called my attention and told me. WHy the heck I asked that question? That my question was dumb, also she added that Im the only person in that group who ask the most questions overall. I guess she tracks me each time I post a question on taht group and check what kind of questions I ask.

My sister thought I was talking about a ping pong table I had at home but we dont use. In my house that ping pong table is being used for another things, like to store clothes and yes it is

a mess the things the table has, but taht is not my sister business anyway. So she told me instead of asking how a ping pong table is repaired, you have to get rid of the table you have at home. She was referring to the ones we have at home. But In my question I was not referring to the one I have at home but to the one my friend has and she need to repair it. I did had to explain my sister that the question I ask was not about our ping pong table but my friend table, and I was doing her a

favor asking it cause she is not a member of this FB group. My sister has to butt in in everything I do and Im an adult The same happened last weekend, I went out to meet for the first time a lady friend I met online last July, cause we had in common a friend who died last July. Well my sister wanted to know who was the lady, and I had to give her her phone number just in case somethign wrong happened. My sister told me I know you are a almost 50 yrd old lady but I have to take precautions
