Is it sad that a commercial makes me teary eyed?

So lately they have been showing this awesome commercial of my home...San Diego, every time it's on, i have to stop what ever i am doing because i love it, i love the fact that they show little scenes of places where i have been and that i miss terribly, but how lame is it that a commercial makes me sad and happy at the same time?? I miss it soooo much, i have been trying to not think about it but sometimes i will be driving and all of the sudden a remember something, either a place or a person that i left behind and tears just start rolling down my face...I miss home...
