I'll be in NY for mothers day so I'm sure to be able to pick up something she'll like over there. Plus I get a few extra days to find something. I hope I don't forget with all the paddy's day celebrations and the rugby and stuff!!!
Ideas... weekend break away is a good one or why not bring her out for dinner and spend some time with her? Not on Mother's Day... bad day to go for dinner but during the week, or the following weekend... spend the whole day doing something with her... things that she likes, e.g. museums, garden centres, etc (i know they can be boring but you do it with the person cause they like it)! Personally I know I don't always get the opportunity to do something like this but it is always a good one compared to "here's your present". Spending time with someone is better IMO!
