am I a cheapskate?

I have just over one glass' worth of wine left in the bottle, and this little hunk of cheese. Would I be considered cheap if I just cut it into little tiny pieces so as to try and make it last through the wine, solely because it's cold out and I won't go to the store just for another block of cheese?

Also, I actually cheated on my boyfriend last week when I was on vacation, and it was fucking awesome. Is that bad, also?
