    My wife and I went to this vegan(严格的素食主义的) restaurant to give it a try. As we were eating our pepper and salt tofu, a young lady named Debra walked in. She wasn't aware that the place is vegan and was looking for some meat. My wife and I talked up the place and invited her over to try some of our tofu. Debra tried it, nodded and went out.

After a few minutes, she and her mother both walked back in. We were having the rest of our meal at that time, so we told her what we had ordered. Debra then asked the waitress to just repeat our order for them. Next , Debra said. "And we want to pay for their meal", pointing to my wife and me. We tried to say no, but Debra wouldn't listen.

That was not the end ofit. Hugs were in order. Debra came over to our table and my wife got up to hug her. Debra hugged my wife and put $ 100 into her hand. My wife firmly said NO, but Debra insisted. Debra kept talking about our kindness, and we did the same about hers and her mother's.With tears in the eyes, the workers were blown away by this whole exchange between four strangers.I left the waiters and waitresses a tip that would cover all ofour meals and we were on our way.

I've been witnessing so much kindness, especially over the last few years, as I began to pay more attention. We now have a new favorite restaurant and every time we go there my plan is to pay for someone else's meal.
