I was assigned yesterday!

This is the first time I was assigned. I was in a cheap calendar on BAC. It was a ITM Put calendar put on for $0.05.
On Friday I saw that the short put (March) had no premium left and was debating whether I should close the position and take a loss of $5/contract or see if the stock will move up (in my direction) on Monday (I wouldnt say Greed here... but something similar... maybe wanting to be right.)
Since the max loss was only $5/C, I took the risk. I had 7 contracts.
On Monday morning, I had 700 shares in my account with stock $2.5 OTM. My long put had about $0.05 of time value. I had the following options:
1) Sell the Put and Sell the shares
2) Exercise the Puts

I was not sure and I wanted to be out of this position. So I spoke with the TOS helpdesk. The person waled me thru the analysis and we concluded that exercising my put was the best bet.
So thats what I did!

If I would have closed the trade on Friday, I would have incurred a loss of $35 + 6 (commissions) = $41
As I had to exercise, my loss was $35 + $3 (commission for buying calendar) +$15 (commission for exercising) = $53.... I lost 30% more because I didnt follow the rules!
