Pre-Christmas shopping has now reached epic proportions; presumably most people missed the memo that the shops re-open in a few days (even on Boxing Day, amazing non?) and there is no need to stockpile like we're just about to enter WW3.
Giving presents is part of Christmas, but it is only a small part of it; the pressure to buy things and "create a holiday" can be very stressful and is unrelated to what many consider the original reason for Christmas, to celebrate the birth of Christ.
Even though Christmas may have now morphed into a secular holiday for many people, I think it is important to remember , religious/obeserving or not, to enjoy it and spend the day with family, friends and/or loved ones.
These times are precious and laughter and memories last a lifetime much more than the latest gadget or "in" thing.
