It's sometimes scents that do it for me. My sister is having a new house built, so she sent a load of kids' stuff her children have outgrown to Aillidh. And when I opened the box I could smell the scent of her house - she makes her own potpurri from flowers she grows in her garden and is always cooking and baking. Her house smells like heaven. It made me think of happy times at her house.
Or my dad will send me a little something he knows I used to love - like a box of Fiddle Faddle or a can of Bush's baked beans.
My dad left his own native city for a better life, so of all people he understands. All I ever wanted in life came to pass here.
My mom knew how much I wanted a family and a home, and how I'd been searching for them for years. She was with me when we first came here on holiday years ago, and one night when we were walking back to the B&B from a night down the pub, she said, 'I think you'll come back to this place and stay here.' And sure enough, I did.
They adore my husband and in-laws and know how very happy we are here.
I miss them, but the rest is just nostalgia, like otterpop pointed out. I know if I went back to Denver I'd be as unhappy there as I was when I left once the novelty wore off, and that things wouldn't be the same.
Getting a car has helped so much, tho! I mean, really, Ulster is SUCH a beautiful place, like Scotland, which you can see from some parts of Ulster on a clear day. Just making a point to find out more, see more, and explore has made me realise all the more how much I love our home here.
