You live abroad, it was a choice you made not your friends, they have made an effort to send you cards, be they real or electronic, just because you have your life planned around who gets sent what when doesn't mean they do the same. If their values said that each of their friends calls round for coffe morning every Monday, would you ? Of course you wouldn't, and living in a different country is a good excuse, but, it's an excuse that you created. You have friends, they have sent you cards, or texts, sometimes we remember things too late, and knowing , or not knowing, how long International mail takes they used another method, who is to say that in 50 years time we'll have birthday "cards" think of the waste, the trees, the manufacturing, the pollution getting it to the shop, you getting it home, the mail delivering it.... You just wanted loads of cards to show your neighbours how popular you were, and still are, back at home, to your friends the e-cards, the calls and the texts were that.
