Technology today has made communication so easy. We've not only improved how easy it is to get in touch with a person, the quality also improved, often including video teleconferencing. However, it's no substitute for actually being with that person. The picture shows my nephew (in the background), who's living with us now, and on the iPad is his mom trying to talk to us. No doubt, I bet she would much rather be here with us instead of seeing her son on the iPad screen... Physical presence trumps all.
I guess it comes down to not taking each other for granted, especially with the people around you today. So, remember to put the camera down for a while and just enjoy each other, a note to self ;-)
