I have lost some plants too. They're at my parents place out of town. Most of the time I do not notice them lost until I specifically want to look for that species when someone ask. Usually it's TS... haa, haaa... He'll be asking me, "eh, how's your N. etc. etc..." Then I'll be like... Hmmm... now that you mention it I've not see it in a while.

Then only I realise it's gone. I'll be frantically asking my parents about them and whether they gave that plant away, but they never give my plants away without asking me after the N. sumatrana insident.
