I am not a horticulturist

I let my houseplant have some fun in the sun on Wednesday. The care tag that come with it said that it does best in medium shade with water every few days, but I thought it was looking rather sickly and that a little bit of sunshine might do it good.

On Thursday, the leaves were no longer green with white spopts, but a green-tinted white with white spots.

Today, my plant looks like this:


That's the third plant that's died on me in as many months.
