You’ve sent a birthday wish to someone via SMS. But since it’s been a while since you last called, you have a little doubt that they may not have got it.
They haven’t responded.
Do you try to contact them some other way? Especially as the birthday is now slipping further into the past? Do you take it as a subtle hint that they don’t wish to talk? Tell me what I should think, dear internet!
No many actually reply to happy birthday sms!
They know you remembered, and I am sure they are very pleased.
But if they reply every happy birthday sms, they’ll be broke!
