I have noticed this with a lot of friends/colleagues. Or may be its me who is only into this, I thought, till couple of days back.
I tend to wait for people to come and join, even after an event, could be after lunch, shopping etc etc. For eg: I go with colleagues for lunch. After the lunch, they just leave without waiting for others to come. I feel its a bit awkward, others may not.
We visited a friend over the weekend. Chinni was also with us, obviously. Chinni got mingled with my friend and his wife in about 10 minutes, that was little fast than normal. Spent some more time with them and I decided to drop them to a near by restaurant. We all started towards my car, while my friend's wife was locking door and was left behind.
As we started moving, Chinni noticed that my friend's wife is left behind and said "ಆಂಟಿ ಬರಲಿ , ಎಲ್ಲರೂ ವೇಟ್ ಮಾಡಿ " (let aunty also join us, wait).
I smiled :)
