Yah I was thinking of writing that when I was typing the sneezing one but forgot lol.
For the someone thinking about you, its normally associated with a fit of coughs...but yes can be many sneezes in a row too etc.
Yes the timing omen is there (for sneezing) as well along with other distinct sounds (like crow cawing, gecko lizard tutting, dog barking etc) to at least make you think twice/ use caution or avoid if possible etc.
We also have a custom for ashirvadam from elders (parents, grandparents, whoever is most senior in the particular place of departure) to prostate at their feet before leaving on big journey (and will be away for significant time etc) for their blessings.
Type of prostrating (mostly at temples or during home shrine worship) is different for men and women. Men do the full body to the ground one when possible, women do the more modest one (head and knees).
Also at temples we are very strict to follow a few principles in the visit: the temple must be circumambulated overall after obeisances are paid to the deities individually, vastu principles must be followed when washing legs and hands before entering, a final prostration must be done to the main deity at the end of worship (my family normally does it at right angles to the sanctum corridor rather than parallel) and we must sit down inside the temple at least for a few minutes before leaving. When back at home, feet must not be washed immediately when returning from temple (unlike regular excursions)....again you must sit down for a while.
You have anything similar to these? It stems from the energy philosophy that
@utraash was talking about earlier.
Many of my relatives live in Bangalore it must be said (and they take the side of Karnataka for Cauvery dispute and other such things).
We all for most part originate from Coimbatore....and going way back, from parts of Kerala. Kerala and TN have a shared history. Their script today is much closer to the older Grantha script of older Tamil-Malayalam language....whereas we changed it somewhat in Tamil.
