I have just had the most amusing conversation with my little brother (well not so little hes 23) it went something like this.....
Bro: well have u got me my present yet? I got u a present
Me: Not yet, did u get me anything?
Bro:

well actually no.. I haven't got u anything yet... I'll get u one if u get me one
Nice to see the Christmas spirit is alive and well isn't it?
