K.,
You are very lucky to have both of your parents living in your home town. Take adavantage of it & talk to your dad/spend more time with him. You didn't mention any issues you may have had w/your dad, which might be a reason you don't talk to your dad more? My own dad moved to the East coast after I graduated from college, got a job & my own place & I only saw him once a year around the holidays, but tried to talk to him on the phone as much as I could, which sometimes ended up being only once/twice a month. Of course he came down when I got married & I did go up to visit him once as well, but I still wish we had more visits & had more frequent phone calls b/c he passed away suddenly 4 1/2 years ago when I was only 30 years old. He never got to even meet my twins b/c I got pregnant w/them a few months after he passed, but he was in the loop when I was trying to get pregnant b/c he was looking forward to grandchildren.
Anyway, what I'm trying to say is to appreciate the situation you have & try to call/spend more time w/your dad b/c you never know what may happen, as life really is short after all & you don't want to regret what you wish you "could've" or "should've" done.
Also, to turn the tables a bit - say your own kids are grown up w/their own families & you're a grandmother as well as a mother - how would you feel if your kids/grandkids only called you once a week and/or didn't spend much time w/you when you are living in the same town? I know life gets busy & if time can't be spent, hearing someone's voice truly goes a long way. There's wireless ear pieces for phones so that you can "do stuff" while you are on the phone w/your dad if that's an issue. That's what I do w/my mother-in-law b/c she likes to talk (LOL) & instead of rushing her off the phone b/c I have stuff to do, I just pop in my ear piece & go about doing whatever I need to do b/c I know she 'needs' to talk. My own mother fortunately comes over 2-3 times a week b/c she does live in the same city & my father-in-law comes once a week, but we do email several times during the week.
Spend as much time/call as much as you can b/c you can never get that time back...
