Let me tell you a little story....
When I was very small, I have always wnated to be a gardner on TV(and this is while I was living in Bosnia, meaning I was 7 and below) I also LOVED plants(and still do) and I also loved picking flowers. Whenever there was a pretty flower, on the balcony or by the roadside, Id pick it.
Nothing on grandmas balcony could blooom properly without being picked.
But one day that all changed.
My stepdad came along, and I picked some lipa flowers(very beautiful tree which produces masses of fragrant flowers) and I went and showed it to him.
He then said: "Did you know that that flower is dead?" And he explained why it was dead and wouldnt survive and all that, from that day on I have NEVER picked a single flower. EVER.
