I have just started in a new school. I'm Irish and in practically every class my accent has been mimiced by students. I have also been repeatedly asked to repeat words beginning with "th" the implication being that I will pronounce "th" as "t" ie. Tursday the tirtiet ... etc. I have been asked if I am a "traveller". I have heard the word "p-i-k-e-y" being murmured about me. I don't know how to tackle this or if I should just ignore it.
