y'a t-il des fautes dans mon texte en anglais svp ? je vous remercie par avance

"I have something unbelievable to tell you; you know last night it was the big Christmas party at home, and mum had invited all the neihbors who wanted to come, family's tradition. But this year, she told me we had a new neighbor... I said "great, I love to meet new people" In my head I already imagined him handsome, single and looking for a girlfriend that could be me...

All the guests arrived, one after another, no new neighbor... mum was busy preparing the turkey when someone knocked singing the christmas "anthem/song?" I opened and there was .... MR STEEVE, my mathematic teacher ! He said "make room to your new neighbor !"

I've been lying to my mum about my math grades all year long (and I still do) and he was about to ruin everything on Christmas ? great...

Result : he spent all night long making fun of me talking my mum about how lucky she was for having given birth to a genius... my poor mum was so proud . How could he have been so crual??

The more time went, more the humilation continued. at table, he asked me to calculate the surface area of the table! I almost choked with my turkey's leg. I didn't even remember how to calculate this.
Fortunately, I succeeded to escape pretending a pressing need. Finally i stayed in the bathroom until he left. I said I didn't digested the turkey

Worst Christmas party ever! "
