Dead Plant?

For quite a long time I had this "flower" plant resting right beside the kitchen/ dining room window. To be honest, I rarely water it since I always, ALWAYS forget. Usually it gets like a big amount of water this one day in a month. It never bloomed but it's still green. You know, with some dead brown leaves hanging off the side and to this day I wonder, "Did it die?" I don't actually know the answer. :/ It's still mostly green so it must mean that Planty survived right? Yep, that's the plant's name, Planty. :) I'm not good with names... I really hope that I'll start remembering to water the poor plant otherwise it'll end up like all my other dead plants that died of dehydration. C: Yep that's right, MANY died. First there was the strawberry plant. I think that was also since it didn't get enough sunlight... I put one of those bulbs that water the plant for you. C: It's too big for any other plant though. Oh well. :| Then there was the tomato plant which grew to fast and I didn't know how to transfer it into a bigger pot. So the pot or "home" was too small for the growing tomato and it DIED. Then there were the 18 bean plants that died since I forgot to water them. C: Yeah... I killed a whole TON of plants. I should really just remember to water them huh?
