Phalaenopsis blooms lasting 7 months!!!

[bigbullits]

I received my light pink Phalaenopsis for my birthday last year (Oct 7, 2008) When I received it all stems were bloomed, there is even another kind of orchid in the same pot that was already flowered. Since then that orchid has lost all flowers but the pink Phalaenopsis has kept its same 6 flowers since then, they are practically perfect! IS THIS NORMAL? Ive read that they normally last 1 maybe 2 months but mine are going on 7 and going strong! I have been taking pictures every few weeks and like i said they practically look like they've just bloomed!
