What you have here is not a sentence.
You are joking but you are serious?hey I was joking about the gift seriously and yes you are late but any ways atleast you dont forget to wish me thank u........day was amazing missed both of u............
He wished you a "thank u"?
Perhaps you mean this: Hey, I was joking about the gift. Yes, you are late, but at least you didn't forgt to wish me a happy birthday. Thank you. The day was amazing but I missed you both.
Please don't use "u" insetad of "you" in forums in which you are trying to improve your English, and do learn to use periods and commas instead of a random number of dots to stand in for all sorts of punctuation.
