Why I hate birthday wish?

Source: Wikipedia

I joined my dream company. They placed a red carpet to welcome me

The first day the CEO met and told me how critical my role is to the company

The first month, the team celebrated my accomplishment

At the end of first year, I won an award at the company event for exceeding expectations

They gave me a birthday card on my birthday

Today, the company eliminated my position — Apparently they have been planning this layoff for the last 6 months.

If so, I wondered how shallow their birthday wish was.

Why would they send me a birthday wish last week, when they knew that my job would be gone in a week?
