For that opening sentence, I'd go with something along the lines of this:
"If I had to summarize my summer vacation, I'd say it was uneventful, but enjoyable."
"My summer vacation was busy to say the least."
"I didn't have the best time with my summer vacation, but it certainly was a vacation."
"I spent my summer vacation the way kids are supposed to; doing absolutely nothing."
"This year's summer vacation was the best I've ever had, and I'd love to tell."
Explanation:
Well technology is far more advanced than what we had decades ago. so it takes a simple lab test to see what you affected by. And also we have had more time to study what each allergy does and what symptoms may be involved in it
I can just give you a suggestion of a story that I have watched. It's " How the Grinch stole the Christmas". The theme of the cartoon is that Christmas is not about presents. One evidence from the cartoon is that after Grinch stole all the presents from the people's houses, they were still happy and they were singing together by holding hands like the presents were nothing for them. At the end the Grinch realized his mistake and gave back all the staffs that he stole.
I hope it helps a little.
