Really worried about my daddy... I feel so guilty that he's so lonely... but it's not my fault my parents isolated themselves to the point where they rely on my brother and I to always keep them company... and it works both ways, they could easily find time to come see us or my brother and his family... but there are always excuses. and I feel guilty for it... sorry for the ranting...
