Wow! Yes, he does seem to be getting his facts extremely mixed up, to say the least. However, on closer examination there are certain "grains of truth" (or in this case "half truths")...for example the statement that Alexei "tried to kill himself". Obviously we all know that the Tsarevich did not attempt to commit suicide, BUT taken in a more figurative sense, it could be referring to the various escapades such as riding a toboggin down the stairs etc etc. Seems as if this teacher is CONFUSED and inaccurate. Problem is, it is very difficult to correct teachers...my son tried it once when his English teacher made a very obvious mistake and instead of thanking him she gave him detention and criticised him dreadfully for the rest of the school year (I felt she deliberately withheld marks in various tests, but obviously we could not prove anything). I attempted to pour oil on troubled waters on a few occasions, but to no avail, and to have complained would only have made the situation worse. Thankfully the teacher left the school a short time afterwards. Anyway, I do sympathise, as such problems (i.e. ignorant teachers) are not easy to deal with.
