Please help! 6 am this morning yesterday 2 days a minute Christmas midnight noon hours Which one word (from the above list) can be used with both For and Since expressions?

What makes a teacher memorable? First of all, I think it is teacher's traits. I mean that, in my opinion, a genuine teacher should take his part properly. You know that nowdays some teachers educate and teach children wrong. Why? Because they don't understand how to be a genuine teacher. Personally, I think that a teacher on the one hand should be kind, calm and benevolent, but, on the other hand, he ir she should be strict, fair and responsible. In my opinion a teacher should set an example to his or her pupils by own behaviour.
