Wow, today is the day for gifts

So first I got a fruit basket delivered today from one of my accounts.  Very nice.  Then I got my mail and there was a X-mas card from our next door neighbor. They are retired, in their 80s, and live in Florida for the winter.  Since we live in an area that has plenty of snow, we (usually me) shovel or snowblow their sidewalk whenever needed.  In the past they have always sent a X-mas card with a check for my husband for doing the snowblowing, I think usually about $50.  This year in their X-mas card there was a check for ME for $200.  I am so shocked.  I very much appreciate it, but it certainly is not necessary and I almost don't want to cash it because it's so much.  But I also don't want to offend them by not cashing it.  But $200--- that's just so much and they did not need to do that.  And oh nooooo, I did not tell my husband I got it!!!  I wish they would just send a card and not feel they have to pay us for doing their walk.  The last thing they need to do is give their money to a neighbor.  On top of it, we have full use/access to their garage while they are in Florida so we can use that for whatever type of storage we need.
