Well- French is one of those languages, like English, that has lots of silly rules that can't be explained! There's no way of telling which ones will take avoir and which ones will take être, unfortunately you've just got to learn them! However, don't worry- there's a really easy way to remember which ones they are! Just remember the name, MRS VANDERTRAMP- each of the letters in her name is one of the verbs that takes être.We'll run through them and then see how quickly you can say them all in order in one go, I can do it in 7 seconds- I challenge you to beat me!
