Signs You've Found Your Sarcastic Best Friend For Life...
'I hope you have 'such' a 'great' day.' Sarcastic friends are the best. Never taking themself or anything too seriously but enjoying the hell out of life. Granted, most of your other friends will just assume that the two of you hate each other and are really mean, you know the truth: that your day is better because they made fun of you for the entirety of it.
