How about I take the bluetooth speaker from the family kitchen?
You should keep all your things in proper places to avoid this issue.
Yeah but it is shitty when other people take things too.
It is wrong to steal things that don't belong to you. You can buy your own speaker for very cheap if you need one.
I didn't say I need one, I'm just thinking of taking it.
That would look poorly on you if you did that. You shouldn't steal things. Others might do that, but maybe setting a good example might be helpful.
