Okay, today's questions.

1) It's almost the same as this:

But the reason is a little different for that. Now it's all about not letting someone move too fast and if they move too fast you will restrain them by slowing them down, but it's not that you push them or drag them, you at least try to do that gently and you certainly don't restrain them from moving wherever they want. Strangely I would use the same Russian word for that, which is придерживать

2) What word do you use to generally describe a process of repairing a house (like renovating it, putting up wallpapers etc). We say ремонт here.

3) This one is not very pleasant but how do you call those things that sometimes clump together in your nose out of nose slime We say козявка or казюля here
