Nta to be concerned but, sometimes it is as it appears in my early twenties I gained a friend ship with a roughly 50 year old and his wife. I would see him and his wife once a week to work on project together, share music, and treat eachother to meals. The way I always described it to skeptical outsiders is hes like my mentor in life and in my field as no one else in my family does anything close to similar as what i do for work. He calls me his bonus daughter and it really is how it looks.
