Проверьте ошибки, пожалуйста. Очень нужно. A joke is about Pat who worked and lived with his wife in England. One day, they have received a telegram which stated that the mother was ill. The wife went to Ireland to see her. Pat deceided to write a letter to his wife but for that he needed priests help. The priest agreed and they began to write. At the end of the letter the priest asked if Pam wanted to say any more. The man asked to apologize for his illiterac and a bad handwritng.

Пока что вот это, но скорее всего я что-нибудь ещё допишу:
The joke - тут конкретная смешная история имеется ввиду, полагаю артикль должен быть определённый
просто received без have
в этом же предложении концовку лучше "a telegram which started with a notification about Pats mothers illness" или чья там мама заболела я понять не могу
but for that he needed priests help тут местами поменять: but he needed priests help for that
if Pam wanted to say any more. слово any лишнее
and a bad handwritng. - артикль "a" здесь не нужен
