Ok, you got to know, I have bad knees. I struggle to stand after I sit, I struggle to walk, and I can trip over a feather.
I think "meet and greet" should be done at the door, not from the seat. If I want to sit and be still before God while all around me is confusion, laughter, worldly noise and jesting before the service starts, then don't expect me to be "glad you came" latter in "the service."
If you want to jest, laugh, shake my hand, or whatever, do it at the entry of the church. And lets let the worship be worship, and the place of worship be that which one can spend time in earnest fellowship with the Scriptures and the Holy Spirit.
Btw, a strong handshake isn't how tight one squeezes. It is the earnestness behind that handshake, the understanding that tired bones don't often grasp very well, but the desires of the heart isn't in the muscular strength. Don't shake my hand and then be rude trying to get out of the parking lot or bully the waiters at the diner.
