   un tad es katru dienu būšu pie tevis, tēt! ― and then every day I'll be with you, dad!

   tagad rakstniecei 71 gads, tēvs miris, kad viņai bija trīspadsmit gadi, bet viņa mums stāsta par savu tēti, it kā tas vakar būtu aizgājis ― the writer is now 71, (her) father died when she was 13, but she told us about her dad as if he had gone yesterday
