Should I Send This Card Or Not?

[bluefortress]

A work collegue is leaving and I bought him a card but did something stupid and spelt a letter of his name wrong - in my defense there are 2 ways of spelling the particular name. 
 

Anyway I was going to throw out and buy a new one but he is the type to call people out on wasting paper etc. So after the 'thanks for being a suportive collegue' message I have put 'sorry about mispelling your name- I was going to discard the card and buy you a new card but I know how passionate you are about wasting paper

At first I thought he might find it funny as he has a sense of humour, but then part of me thinks it sounds sarcastic. 
 

What do you think.. should I sens it him or get a new card.

The fact that it's bothering you ....   I would buy a new card

Difficult to say without knowing you both, but I think I would tend to leave it.

Buy a new one and don't tell him about this one.
