Ab khul ke saamnay aa'yeen naa .. Granny shranny ka to bahana hai, pyar ka silsila purana hai
LOL :p
you are now acting like that nosey gossipy aunty rather than the perv uncle as some1 else earlier ilzamofied you :p
And MB ... just be cautious while he is around. If nothing works you can always go to your extended family's place. cousins etc. Maybe you could talk to your Gran if he does try that inappropriate perv behavior.
but the best option would be AVOID and IGNORE and be cautious :)
Good luck :)
